Application of titanium rod, titanium wire and titanium plate in electric power industry

1. Aerospace

The major titanium use countries in the aerospace industry are concentrated in Western countries, especially the United States, where 60% of titanium is used in this field. Asian countries, Japan and China all invest about 10% of titanium in this field. However, with the rapid development of Asian aerospace in recent years, the consumption of titanium in the aerospace field will increase accordingly. From a global perspective, the aviation industry plays a decisive role in the titanium market. Historically, the major cycles of the titanium industry are closely related to the aviation industry.

2. Civil aircraft

(1) Reduce structural weight and improve structural efficiency

(2) Meet the use requirements of high temperature parts

(3) Meet the requirements that match the structure of the composite material

(4) Meet the requirements of high corrosion resistance and long life

3. Military weapons

The development and procurement of military weapons continue to develop in the direction of lightness and flexibility. In order to meet the fighter's combat performance requirements, in addition to the use of advanced design technology, it is necessary to use materials with excellent performance and advanced manufacturing technology. One of the important measures is to choose a large number of titanium alloys and improve the application level of advanced titanium alloys.

4. Car

Reducing fuel consumption and reducing hazardous waste (CO2, NOX, etc.) emissions have become one of the main driving forces and directions for technological progress in the automotive industry. Research shows that lightweight is an effective measure to save fuel and reduce pollution. For every 10% reduction in the quality of a car, fuel consumption can be reduced by 8%-10%, and exhaust emissions can be reduced by 10%.

In terms of driving, the acceleration performance of the vehicle is improved after the weight is reduced, and the vehicle control stability, noise, and vibration are also improved. From the perspective of collision safety, after the car is lightweight, the inertia during a collision is small and the braking distance is reduced.

5. Medical industry

Titanium has a wide range of applications in the medical field. Titanium is close to human bones and has good biocompatibility to human tissues without toxic side effects. Human implants are special functional materials closely related to human life and health. Compared with other metal materials, the main advantages of using titanium and titanium alloys are as follows:

1 Light weight; 2 Low modulus of elasticity; 3 Non-magnetic; 4 Non-toxic; 5 Corrosion resistance; 6 High strength and good toughness.

The amount of titanium alloy used in surgical implants is increasing at an annual rate of 5%-7%. Femoral heads, hip joints, humerus, skull, knee joints, elbow joints, shoulder joints, metacarpophalangeal joints, jaws, and cardiac membranes, kidney membranes, vasodilators, splints, prostheses, made of titanium and titanium alloys Hundreds of metal parts, such as fastening screws, have been transplanted into the human body. Good results have been achieved, and they have been highly praised by the medical community.

6. Chemical industry

Titanium has excellent corrosion resistance, mechanical properties and process properties, and is widely used in many sectors of the national economy. Especially in chemical production, titanium is used instead of stainless steel, nickel-based alloys and other rare metals as corrosion-resistant materials. This is of great significance to increase output, improve product quality, extend equipment life, reduce consumption, reduce energy consumption, reduce costs, prevent pollution, improve working conditions, and increase labor productivity.

7. Ocean Engineering

With the development of science and technology and the depletion of land resources, mankind's development and utilization of the ocean has been on the agenda. Titanium has excellent corrosion resistance to seawater, and is widely used in seawater desalination, ships, ocean thermal energy development, and seabed resource exploitation.

8. Daily life

Titanium is widely used in daily life and can be described as ubiquitous. For example, golf heads, bicycle frames, tennis rackets, wheelchairs, spectacle frames, etc. are all used in titanium.

The application of titanium in sporting goods due to its light weight and high strength has gradually expanded from the earliest tennis rackets and badminton rackets to golf heads, clubs and racing cars.

The light weight of titanium is also applied to spectacle frames, and titanium is not easy to be allergic to the skin, and the surface of titanium can have brilliant colors after anodizing, so it has been used in spectacle frames since the early 1980s.

Titanium is considered a rare metal because it is scattered in nature and difficult to extract. But it is relatively rich, ranking tenth among all elements. Titanium ore mainly includes ilmenite and rutile, which are widely distributed in the crust and lithosphere. Titanium is also present in almost all living things, rocks, water bodies and soil.

The Kroll method or Hunter method is required to extract titanium from the main ore. The most common compound of titanium is titanium dioxide, which can be used to make white pigments. Other compounds include titanium tetrachloride (TiCl4) (used as a catalyst and used to make smoke screens as air cover) and titanium trichloride (TiCl3) (used to catalyze the production of polypropylene).

Titanium alloy characteristics:

High strength, the density of titanium alloy is generally about 4.51g/cm3, which is only 60% of steel. The strength of pure titanium is close to the strength of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much greater than other metal structural materials, and parts and components with high unit strength, good rigidity and light weight can be produced. At present, titanium alloys are used in aircraft engine components, skeletons, skins, fasteners, and landing gear.
