1. Aerospace
Titanium used in aerospace is concentrated in western countries, especially the United States, where 60 percent of titanium is used in this field. Asian countries, Japan and China have all invested about 10 per cent in the sector. 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 temperature and temperature of 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 of matching with composite material structure
(4) meet the requirements of high corrosion resistance and long life
3, car
Reducing fuel consumption and emission of hazardous wastes (CO2, NOX, etc.) has become one of the main driving forces and directions of technological progress in the automobile industry.
Research shows that lightweight is an effective measure to save fuel and reduce pollution. A 10% reduction in the quality of a car saves 8-10% in fuel consumption and 10% in emissions.
In terms of driving, the acceleration performance of the vehicle is improved after being lightweight, and the control stability, noise and vibration of the vehicle are also improved. From the perspective of collision safety, after the car is lightweight, the inertia is small and the braking distance is reduced.
The preferred approach to automotive lightweight is to replace traditional automotive materials (steel) with lightweight materials of high specific strength, such as aluminum, magnesium and titanium. The amount of titanium used in automobiles reached 3,000 tons in 2009. Titanium has been used in car racing for many years. At present, almost all car racing cars are made of titanium. The titanium used in Japanese cars has exceeded 600 tons.
