What are the applications of titanium alloy in the automotive field?

1, titanium alloy engine connecting rod - titanium alloy with its advantages of lightweight, used as connecting rod material is very rational. Compared with steel links, titanium links can reduce the weight of 15 to 20 percent. The first car to use titanium rods was the Ferrari 315LV8.

2, engine valve - titanium alloy automobile engine valve light weight, long service life, but also reduce fuel consumption. Compared with the steel engine valve, the mass can be reduced by about 30%-40%, and the engine limit speed can be increased by about 20%.

3, valve spring seat - titanium alloy high strength and fatigue resistance advantages just fit the characteristics of the valve spring seat, titanium alloy valve spring seat than steel mass reduced by 30%-40%, so that the valve structure reduces the inertia mass, the maximum engine speed can also be increased.

4, titanium alloy spring - titanium alloy has a low modulus of elasticity, compared with steel spring, under the premise of providing the same elasticity, titanium spring height is only 40% of steel spring, quality is only 30%-40% of steel spring, to bring more design space to the body. In addition, the service life of titanium alloy spring is much longer than that of steel.

5, turbocharger transfer rotor - titanium alloy has good heat resistance, and good processing type. The rotary rotor of the turbocharger works at 850℃ for a long time, which gives titanium alloy a good space to play.

6, exhaust system and muffler - titanium alloy is widely used in the automobile exhaust system, performance, prolong life and appearance have been improved, improve fuel combustion efficiency. Titanium exhaust system than steel exhaust, the mass can be reduced by about 40%, generally about 5 kilograms of mass.

7, the body frame - part of the titanium alloy high strength, good toughness, is the ideal material for making the body frame. Japanese automakers use titanium to create body frames for better driving experience.

8, titanium alloy hub bolt - titanium alloy bolt is modified hub is an essential part, not only light weight, strength is higher than steel bolt. The special luster is also a good decoration on the wheel hub, improve the appearance level.

9, other titanium alloy parts - in addition to the above parts, titanium is also used in engine rocker arm, suspension spring, engine piston pin, vehicle fasteners, hanging ear nuts, car door burst beam, car bracket, brake caliper piston, pin bolt, pressure plate, shift button and clutch round plate and other automotive parts.

The application history of titanium and titanium alloy is not long, but its comprehensive performance is very good, light weight, at the same time has good corrosion resistance, toughness, workability, weldability; Low thermal expansion coefficient, low thermal conductivity, no magnetism, no pollution to the environment... This is why the company has made great achievements in fields requiring extreme technology such as aerospace and medical treatment.
