What are the main mechanical properties of titanium rods?

The mechanical properties of titanium rods mainly include tensile strength, yield strength, elongation, shrinkage, etc. These performance indicators can reflect its performance under external forces, which is of great significance for its application and safety of use.

1. Tensile strength: refers to the maximum strength of titanium rods without breaking under tensile force, usually expressed in MPa (megapascals). Tensile strength is a very important indicator of its mechanical properties, which can reflect the strength and bearing capacity of titanium rods under tensile force.

2. Yield strength: refers to the phenomenon that the deformation of titanium rods suddenly increases when they are subjected to external forces less than the maximum tensile stress, usually expressed in MPa. Yield strength reflects its strength and bearing capacity when subjected to plastic deformation.

3. Elongation: refers to the maximum elongation of titanium rods before breaking under tensile force, usually expressed in percentage. Elongation reflects its plastic deformation ability and can reflect the overall plastic properties of titanium rods under external forces. ASTM F136 6Al-4V ELI Titanium Bar / grade 5 titanium round bar / titanium rod grade 5

4. Shrinkage rate: refers to the degree of cross-sectional shrinkage of the titanium rod under compression, usually expressed as a percentage. The shrinkage rate reflects its compactness and stability under compression.

In addition to the above mechanical performance indicators, titanium rods also have good corrosion resistance and high strength, and are suitable for various high-demand application scenarios. At the same time, its mechanical properties will also be affected by factors such as production process, ambient temperature, and loading speed. In actual applications, it is necessary to select and optimize according to the specific use environment and process requirements to ensure its safety and reliability.

What are the fixing methods of titanium coils?

There are two main fixing methods for titanium coils: detachable and non-detachable. The choice of these two fixing methods mainly depends on the specific application scenario, the medium properties of the material, and the corrosion of the titanium coils.

First, let's look at the detachable fixing method. The biggest advantage of this method is its flexibility. Since the titanium coil may need daily maintenance, overhaul and cleaning during use, the detachable fixing method allows operators to easily disassemble and reinstall the titanium coil, greatly improving work efficiency. In addition, for situations where some media may corrode or need to be replaced regularly, the detachable fixing method also provides great convenience. However, this fixing method may increase the risk of leakage in some cases, so special attention should be paid to sealing during design and installation. Titanium Condenser Tubes / Titanium Coil Tube / titanium threaded pipe

Then, let's look at the non-detachable fixing method. The advantage of this method is its stability and durability. Once the titanium coil is fixed, it will remain stable unless large-scale disassembly work is carried out. This fixing method is suitable for situations where the medium is stable, not prone to corrosion, and does not require frequent maintenance and overhaul. However, the disadvantage of the non-detachable fixing method is also obvious, that is, once maintenance or cleaning is required, tedious disassembly work is required, which will greatly increase maintenance costs and time.

When choosing the fixing method of titanium coils, in addition to considering the above factors, the material and use environment of titanium coils need to be considered. Titanium is a very active metal, but its equilibrium potential is very low, and it is stable and corrosion-resistant in most media. However, in specific media, titanium may also corrode. Therefore, when choosing a fixing method, it is necessary to fully consider the corrosion risks that titanium coils may face.

In addition, for the installation and fixing of titanium coils, certain engineering specifications and safety standards need to be followed. For example, during the installation process, it is necessary to ensure the stability and sealing of the titanium coils to prevent leakage and safety accidents caused by improper installation. At the same time, for the detachable fixing method, it is also necessary to design a reasonable disassembly and installation interface for daily maintenance and repair.

In general, the fixing method of titanium coils needs to be selected according to specific application scenarios and needs. Both detachable and non-detachable fixing methods have their unique advantages and applicable scenarios. When choosing, it is necessary to comprehensively consider factors such as medium properties, corrosion risks, maintenance requirements, and installation costs to select a suitable fixing method. At the same time, it is also necessary to strictly comply with relevant engineering specifications and safety standards to ensure the safe and stable operation of the titanium coil.

What is the difference between pure titanium plate and composite titanium plate?

The main difference between pure titanium plate and composite titanium plate lies in their composition and use.

Pure titanium plate is composed of a single element (titanium dioxide), also known as "glassy" metal, with high purity. This titanium plate has good heat corrosion resistance and stress erosion cracking resistance, so it is widely used in high temperature and high pressure containers in the petrochemical industry, as well as oil production platforms and drilling platform storage tanks in marine environments, etc., as lining materials for equipment or as anti-corrosion coatings. Grade 3 Pure Titanium Sheet / Gr5 Ti-6Al-4V Titanium Plate / Gr7 Ti-0.2Pd Titanium Sheet

Composite titanium plate is a special stainless steel plate composed of two or more elements. These elements may include aluminum and other metal elements such as molybdenum and niobium, so it is also called compound steel or molybdenum-based alloy (mo-alloy) or niobium-based alloy (nicralloy). Composite titanium plate has unique physical and chemical properties due to its special alloy composition, which can meet some special application requirements.

In general, pure titanium plate and composite titanium plate are different in composition, performance and application, and need to be selected according to the specific use environment and needs.

Technological tips for machining titanium fasteners

Use blades with positive geometry to reduce cutting forces, cutting heat and workpiece deformation; keep the blade edge sharp. Blunt tools are the cause of heat buildup and wear, which can easily lead to tool failure.

Maintain a constant feed to avoid hardening of the workpiece. The tool should always be in feed during the cutting process. The radial cutting amount ae should be 30% of the radius during milling.

Use high-pressure and high-flow cutting fluid to ensure the thermal stability of the machining process and prevent surface degeneration and tool damage due to excessive temperature. titanium foil grade 5 / titanium metric screw / Gr2 Pure Titanium Plate

Process titanium alloys in the softest state as much as possible, because the material becomes more difficult to process after hardening, and heat treatment increases the strength of the material.

Use a large tip radius or chamfer to cut in and put as much of the blade into the cutting as possible. This can reduce cutting forces and heat at each point and prevent local damage. When milling titanium alloys, the cutting speed has the greatest impact on tool life vc among all cutting parameters, followed by radial cutting amount (milling depth).

Titanium screws are so widely used, what are their advantages and characteristics?

In recent years, the application of titanium screws has become more and more extensive. Among the screws of the same specifications and models, the price of titanium screws has always been higher than that of other materials, but its performance and application range have irreplaceable advantages over carbon steel screws and stainless steel screws. titanium foil grade 5 / titanium metric screw / Gr2 Pure Titanium Plate

Titanium screw products have the following advantages:

1. Low density and high strength: The density of metal titanium is 4.51g/cm3, which is higher than aluminum and lower than steel, copper and nickel, but its specific strength is the first among the above metal materials.

2. High corrosion resistance: Titanium is very stable in many media, such as titanium is the most corrosion-resistant in oxidizing, neutral and weakly reducing media.

3. Heat resistance and low temperature resistance: New titanium alloy screws can be used for a long time at 600℃ or higher. Low-temperature titanium alloys represented by titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo maintain good ductility and toughness at low temperatures of -196-253℃, avoiding metal cold brittleness, and are ideal materials for low-temperature containers, tanks and other equipment. Most of the titanium screws produced by Shishitong Metal are directly supplied to submarines, aviation power, high-end kitchen utensils, and driverless cars, making them not only resistant to high temperatures, but also able to be used normally at ultra-low temperatures.

4. Titanium is a non-magnetic metal, non-toxic, and will not be magnetized in a large magnetic field. With the enhancement of everyone's health awareness, titanium screws are widely used in medical auxiliary treatment. Titanium screws can have good compatibility with human tissues and blood even in the human body. At present, the main titanium products are heart stents, intramedullary nails, dental implants, therapeutic devices and some physical therapy equipment that have more contact with the human body. The fastener components in these devices must also be titanium products.
