The research status of titanium and titanium alloy for automobile

The largest amount of titanium in car is the country of America and Japan. First of all, American attaches great importance to the application of titanium in the car. For example, Timet set up a special car factory to develop titanium for automotive parts. American has produced titanium intake valves, exhaust valves, valve retainer and a connecting rod and other components for racing car.
As early as 20 years ago, titanium had been applied in racing car and some sports car in Japan, but it wasn't applied in the common car without considering cost. For instance, the Nissan R382 for the titanium alloy valve system won the Japan contest. At present, the main applications of titanium and its alloys in automobile are the engine parts spring, car connecting rod, rod, standard parts, wheels, and power valve. According to the experience of Japan, the titanium 0.8~0.9kg/set used in automobile power valve is equivalent to the effect of weight loss of 20kg/ set.
Our country is vigorously promoting the popularization of titanium for automobile. Firstly, the application knowledge of titanium can be spread to every corner of the society through the website, newspapers, magazines and other promotion forms.
The automotive design of the new generation pays more attention to reduce weight, reduce fuel consumption, and reduce engine noise and vibration, in order to meet the environmental requirements. In this trend, the light metal titanium will become a major application field for the cars in the future. However, titanium parts are still rarely used in automotive. With the development of economy and the reduction of the titanium cost, more and more designers will choose titanium used for automotive parts. Titanium will eventually play a very important role in the automotive industry.
Some suggestions for titanium used in automobile in China:
1. The promotion of titanium used in car still needs a very long time period; it should firstly enter from the high-end market, and then gradually permeate to the low-end models and foreign market.
2. The titanium material with low cost should be promptly developed, and this is the key of promoting titanium used in car.
3. The ability of independent development of the domestic auto parts needs to be improved.
