Up to now, the car has a history of more than one hundred years, is an indispensable means of transportation in our life. The performance of titanium, such as light weight and high strength, has long attracted the attention of car manufacturers. Titanium valley titanium has been used in racing cars for many years, and almost all current racing cars use titanium. However, the general automotive sector is an emerging development market for titanium.
The advantages of titanium materials as automotive parts materials are: high strength, low density, elastic modulus is about half of steel, low thermal expansion coefficient, about half of stainless steel and aluminum, non-magnetic, low thermal conductivity, no pollution to the environment, etc.. In addition in the automotive industry with titanium, can greatly reduce the weight of the car, reduce its fuel consumption, improve the efficiency of the car, reduce noise.
Typical titanium alloy parts in automobiles include rotor blades for turbine chargers made of TiAl, connecting rods and valves made of Ti-6A1-4V, etc. In order to realize low cost, ti-6A1-4Sn-4Zr-1Nb-1Mo-0.2Si-0.3C alloy matrix was added with Ti-MMC dispersed by TiB particles by powder metallurgy method to manufacture engine valve. In addition to connecting rods and engine valves, the original low cost beta titanium alloy TImetaL LCB suspension spring is also an initial application. More recently, progress has been made in the development of low-cost titanium alloys for engine valves and exhaust. In particular, the demand for titanium alloy for motorcycle exhaust system (muffler) is increasing, so the development of low-cost alloy for exhaust system is more prevalent in Titanium Valley nonferrous Metal Trading Center.
