What are the magical uses of titanium wire

The performance of titanium is so excellent, the role of titanium and titanium products has become more extensive. Our most common titanium products are titanium plates, titanium rods, titanium standard parts, titanium dioxide, and even titanium wires. With the continuous research and development of titanium, the application fields of titanium are becoming more and more extensive, and there are more and more titanium and titanium alloys and various titanium products. The following titanium wire manufacturers will take you to see what are the classification and uses of titanium wire.

Titanium wire can generally be divided into surgical medical titanium wire and titanium alloy titanium wire according to whether the raw material is pure titanium or titanium alloy; it can also be divided into α titanium alloy and near α type alloy according to different composition of titanium alloy, (α+β ) Type alloy, near β type alloy and β type alloy. It can also be classified according to the different properties of titanium wires, and can also be classified according to others, but other titanium spring wire are classified according to less, and specific adjustments can be made according to the parameters of each industry.

The basic characteristics of titanium, corrosion resistance, high hardness, no magnetism, high temperature resistance, low temperature, etc., these series of functions have led to a wide range of application fields of titanium products. At present, the focus of titanium application fields is still in aviation and aerospace. , Chemical, medical, automotive, construction, sports, industry, leisure and other fields, so far, titanium is still in short supply, and the development potential is still very large.

What should be paid attention to during the cutting process of titanium plate?

In view of these chemical properties of titanium metal, what problems should be paid attention to during the cutting process of Medical Titanium Plate Grade 2? The following titanium plate manufacturers will tell you.

(1) If it is a semi-automatic cutting, the guide rail should be placed on the surface of the titanium plate, and then the cutting machine should be placed on the guide rail, paying attention to the order not to be reversed.

(2) The cutting parameters should be appropriate, and should be reasonably determined according to the thickness of the titanium plate, so as to obtain a good cutting effect.

(3) Check whether the cutting nozzle is unblocked. If there is a blockage, it should be cleared in time.

(4) Before cutting the Titanium Clad Copper Sheet, the surface should be cleaned and a certain space should be left, which can facilitate the blowing of slag.

(5) The distance between the cutting nozzle and the surface of the titanium plate should be appropriate, too close or too far is not good.

(6) The preheating of the titanium plate should be sufficient, so as not to affect the cutting process.

(7) If you are cutting workpieces of different sizes, you should cut small pieces first, and then large pieces.

Current Status of Domestic Titanium and Titanium Alloy Antifouling Technology

On the one hand, the domestic market for antifouling paints for large-scale ocean-going ships has been monopolized by international multinational companies. On the other hand, my country’s own antifouling coating technology has been in a position of backwardness, imitating and tracking development for a long time. Therefore, my country’s own brand of grade 5 titanium plate Products can only seek survival and development in the cracks between warship painting and the offshore fishing market. So far, the antifouling paint products of our country's independent brands are still dominated by traditional soluble antifouling paints such as blue antifouling paint and chlorinated rubber antifouling paint, and such antifouling paints have been banned and abandoned in developed countries. Compared with developed countries in Europe and the United States, there is still a significant gap in the domestic technological level.

In recent years, the literature and patent reports on new antifouling coatings at home and abroad are very impressive, involving Wuxi self-polishing, controllable dissolution type, biological antifouling, chemical bionics, nano slow-release, alkaline antifouling, biological enzyme antifouling, Low surface energy, conductive anti-fouling, structural bionics, fluorescent anti-fouling and other technical features of Nuoduo. In summary, it can be attributed to two series of release antifouling coatings and non-release antifouling coatings. The release type is still based on the design concept of self-polishing or dissolving antifouling paint, focusing on the research and development of biological extracts or artificially synthesized bionic antifouling agents, as well as biological enzymes and strong substances as antifouling agents, and then developing nano slow-release technologies. The controllable and effective release of various low-toxic, environmentally-friendly antifouling agents in the coating is well-realized, and the purpose of high-efficiency antifouling is achieved. Non-releasing series of antifouling paints such as low surface energy, conductive antifouling, structural bionics, fluorescent antifouling, etc. rely on the specific physical mechanism of the coating to achieve a non-toxic and long-lasting antifouling function map.

Low surface energy antifouling coatings have received more and more attention due to their non-toxic and unique antifouling mechanism. The Luoyang Ship Material Research Institute of my country has been more mature in the research of low surface energy antifouling coatings and has already provided a variety of products for ship antifouling use. However, such coatings have problems such as poor compatibility with primers and poor recoatability. At present, researches on modification of such coatings are being carried out at home and abroad in order to obtain better antifouling effects.

The capsaicin antifouling paint developed by the Second Institute of Oceanography, State Oceanic Administration of my country, is a composite of biologically active substances extracted from natural non-polluting peppers and organic clay. It will not kill attached marine organisms, but only To drive away. The coating has been tested on 7 ships in the South China Sea, the East China Sea, the Yellow Sea, and the North Pacific Ocean. The results show that the capsaicin antifouling paint has obvious antifouling effects.

my country's oceans are vast and there are many types of marine organisms attached, including lime worms, oysters, barnacles, various algae, and branch worms. If Titanium Alloy Rectangular Tube is used in seawater environments, corresponding anti-fouling measures must be adopted.

A variety of methods to prevent marine organism fouling have been studied, such as antifouling paint antifouling, electrolytic seawater antifouling, ultrasonic antifouling, biological antifouling, and low surface free energy antifouling methods. At present, the following measures can be adopted to solve the growth of marine organisms in China:

(1) The sub-exudation type coatings currently used in domestic ships can be used, and the antifouling period is 3 years.

(2) The use of electrolytic seawater for anti-fouling: that is, electrolysis of seawater produces chlorine gas, which is dissolved in water and becomes ClO-1, which is an unstable strong oxidant. As long as its concentration reaches 0.01PPm, it can ensure that sea creatures do not adhere, or Be killed. As hypochlorous acid is extremely unstable, it will soon become NaCl and return to the sea, so it will not pollute the environment.

(3) The use of electrolytic copper and aluminum electrode comprehensive anti-fouling technology: because cuprous oxide is an effective substance to inhibit biological adhesion, copper anodes can be installed on small and medium-sized ships, and Cu + ions are generated by electrolysis through small direct current. When the concentration reaches 5PPb, the adhesion of marine organisms can be prevented. The electrolytic aluminum anode biologically produces Al(OH)3 glue, which can maintain Cu + and make its effect longer. At the same time, Al(OH)3 is attached to the tube wall to prevent corrosion.

What are the methods for mirror polishing of titanium materials

One: grinding

Spread it with 80-mesh water sandpaper and squeeze out the air. The sandpaper is "pasted" on the polishing plate. Turn on the switch of the motor, and grind at the same time as water is supplied. Grind until there is no rough skin on the surface, and then grind it with 320-mesh sandpaper. , Grind the sand pattern to fine, after two minutes, change to 1200 mesh sandpaper to grind to make the surface of the product finer.

Two: polishing (rough polishing, medium polishing, fine polishing, mirror polishing)

1: Coarse polishing: use titanium alloy special hemp wheel or wool wheel and special permanent luminous titanium wax to polish to make the product surface smooth. Pay attention to the intensity of polishing and the direction of product polishing.

2: Medium polishing: Use a titanium alloy special polishing coarse cloth wheel or a fine wool wheel plus a titanium alloy special permanent luminous medium polishing wax to remove the lines left by the rough polishing, and the surface of the product will have brightness.

3: Fine polishing: use Grade 23 Ti-6Al-4V ELI Titanium Bar cotton cloth wheel and titanium alloy special permanent luminous fine polishing wax to make the titanium alloy product reach high brightness. There are some slight cloth patterns on the surface of the product.

4: Mirror polishing: Use a titanium alloy special loose bleached cotton cloth wheel and a titanium alloy special mirror polishing wax to remove the slight cloth patterns on the surface of the product, so that the AMS 4900 CP Titanium Plate mirror can be polished.

However, the above operations require professional polishing hands to meet the product polishing requirements, mainly related to the details of polishing strength, speed, direction, and so on.

Titanium alloy rod material milling processing and advantages

Titanium alloy has high strength, high fracture toughness, good corrosion resistance and weldability. As aircraft fuselages increasingly adopt composite structures, the proportion of titanium-based materials used in the fuselages will also increase, because the bonding properties of titanium and composite materials are far better than aluminum alloys. For example: Compared with aluminum alloy, titanium alloy can increase the life of the fuselage structure by 60%.

The extremely high strength/density ratio of titanium alloys (up to 20:1, which means that the weight can be reduced by 20%) provides a solution for reducing the weight of large components (this is the main challenge for aircraft designers). In addition, the inherent high corrosion resistance of titanium rectangular rod (compared to steel) can save the cost of daily operation and maintenance of aircraft.

Because it is more difficult to process than ordinary alloy steel, titanium alloys are generally considered to be difficult to process materials. The metal removal rate of a typical titanium alloy is only about 25% of that of most ordinary steel or stainless steel, so the time required to process a titanium alloy workpiece is about 4 times that of steel.

In order to meet the growing demand for titanium alloy processing in the aerospace industry, manufacturers need to increase production capacity, and therefore need to better understand the effectiveness of titanium alloy processing strategies. The processing of a typical 6al4v titanium rod workpiece starts from forging until 80% of the material is removed to obtain the final shape of the workpiece.

With the rapid growth of the aerospace parts market, manufacturers have felt powerless, coupled with the increased processing demand due to low efficiency, resulting in obvious tension in the processing capacity of titanium alloys. Some leading companies in the aviation manufacturing industry even publicly question whether the existing machining capabilities can complete all the processing tasks of new titanium alloy workpieces. Since these workpieces are usually made of new alloys, the processing methods and tool materials need to be changed.

Titanium alloy drawing plate deep formability of cylindrical parts drawing

The common deformation methods of Grade 3 Pure Titanium Plate can be summarized into five types: deep drawing, pulsation, flanging, bending and compound forming. However, it is difficult to make a typical test piece if a single drawing deformation method is used. Therefore, the compound deformation method is actually used in the test. In addition, the test will inevitably bring about the influence of mold structure and operating process factors, so the evaluation of sheet drawability is a lot of complicated knowledge. Guozhu’s research work mainly takes the limit drawing coefficient K (LDR) as an indicator, and proposes many evaluation methods from a variety of perspectives such as analysis, testing, and statistics, and solves many problems. However, most commonly used steel and aluminum are the main objects, so they must be modified and supplemented for use in Titanium Clad Copper Sheet and titanium alloys.

The drawing test method of cylindrical parts was proposed by Swift in 1940. It used the stepwise increase of wool to measure the limit drawing coefficient K value, and it was recommended as an international standard by the International Deep Drawing Research Association in 1967. This method has learned a lot The drawing performance of steel, aluminum and copper sheets.

When used in titanium, especially α and α+β titanium alloys, the following problems are mainly encountered:

a. Bending and cracking occurs at the four corners of the punch;

b. Wrinkles and cracks are generated at the round corners of the die.

This is caused by the poor bending and wrinkle resistance of the titanium alloy, and cannot fully explain its deep drawability. For example, TC4 and TA7 boards have poor deep drawing or impossible to draw.

Where is the titanium metal used in high-tech fields?

In daily life, we often hear that titanium is used in some high-precision fields, so what kind of tall metal is titanium? What is unique about it so that it is favored by top products? Today, I will give you a popular science, where is the titanium metal used in the high-tech field?

Titanium is a metal. Titanium looks like steel, with silver-gray luster. The titanium discovered by Gregor and Kraprot at the time was powdered titanium dioxide, not metallic titanium. Because the oxide of titanium is extremely stable, and metal titanium can directly and fiercely combine with oxygen, nitrogen, hydrogen, carbon, etc., elemental titanium is difficult to prepare. It was not until 1910 that the American chemist Hunter made the purity for the first time. Up to 99.9% metallic titanium.

Grade 5 Titanium Tube metal has the characteristics of low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic and non-magnetic, weldable, good biocompatibility, and strong surface decoration. It is a lightweight, high-strength, corrosion-resistant Structural materials are widely used in high-precision fields such as aerospace, medical equipment, sporting goods, and precision products.

Titanium, which is widely used in high-precision fields, is also used on Braun's latest Braun luxury gold 9 series razor. It is reinforced by a titanium coating, which is strong and corrosion-resistant, while giving gentle care to the skin and reducing shaving. Skin is red and swollen when shaving.

The application of titanium in surgical procedures is also worth mentioning. Titanium is "biophilic". In the human body, it can resist the corrosion of secretions and is non-toxic, and it is suitable for any sterilization method. Therefore, it is widely used in the manufacture of medical equipment, artificial hip joints, knee joints, shoulder joints, flank joints, cranium, active heart valves, bone fixation clips

Before titanium, stainless steel bones were usually used. However, the use of stainless steel has a disadvantage, that is, it is very painful to take out the stainless steel sheet after the bone has healed. Otherwise, stainless steel will be harmful to the human body due to rust. If you switch to titanium "artificial bone", orthopedics technology will be completely changed. In the place where the bones are damaged, use Grade 1 Pure Titanium Plate and titanium screws. After a few months, the bones will re-grow in the small holes and screws of the titanium sheets. The new muscle fibers are wrapped in the titanium sheets, and the titanium bones look like real The bones are connected with flesh and blood, and play a role of support and reinforcement.

The characteristics of high strength and low density make titanium widely used in the field of sporting goods. High-quality bicycle frames and golf clubs are usually made of titanium, which is strong and durable.

Titanium is an ideal material for aircraft. Aircraft engines, bulletproof parts, strengthening parts, strengthening parts, combustion chambers, turbine shafts, turbine discs, nozzles, etc., are mostly made of titanium alloy materials, mainly because titanium is good Heat resistance.

With the development and utilization of titanium tubing for bike frame, it has been discovered that titanium is not only an ideal material for aviation equipment, but also a preferred material for building ships and submarines. Titanium has the reputation of "submerged metal". Titanium alloy is a hero who climbs into the sky and a hero who dives into the sea. When navigating in the deep sea, submarines have to withstand tremendous pressure. The deeper the dive, the greater the pressure. The shell of nuclear submarine is made of titanium alloy, and its diving depth is more than twice that of ordinary submarine.

Titanium has a strong resistance to acid and alkali corrosion. It will not corrode after 5 years of immersion in seawater, while steel will corrode and deteriorate in seawater. Titanium alloy is used to make the shell of the ship, and the seawater cannot corrode it. The submarine made of it is resistant to seawater corrosion and deep pressure, and its diving depth is 80% higher than that of the stainless steel submarine. At the same time, titanium is non-magnetic and will not be found by mines, and has a good anti-monitoring effect. Generally, steel submarines are easily crushed by water pressure when they dive more than 300 meters. The titanium submarine dives deeper than 300 meters, not only will not be crushed, but also can effectively avoid depth charges, showing the unique charm and excellent performance of the "titanium submarine".

It can be seen that as a lightweight, high-strength, corrosion-resistant material, titanium is widely used in high-tech fields such as aerospace, military weapons, medical equipment, sporting goods, high-end products, and construction, and more and more civilian fields are also beginning to use it. This metal, in a sense, the use of titanium has become synonymous with high-end.
