Titanium's lightweight and high-strength properties have long captured the attention of automakers.
Titanium has been used in racing cars for many years, and today's race cars are almost exclusively made of titanium. In the United States, titanium intake and exhaust valves, valve retainers, and connecting rods are already produced for racing. The first Japanese car to use titanium was the Nissan R382.
Today, let's explore the specific applications of titanium alloys in the automotive industry.
Currently, titanium components used in automobiles primarily include:
1. Valves.
American manufacturers commonly use titanium alloys for intake and exhaust valves, with Ti-6Al-4V titanium alloy bars used for intake valves and Ti-6Al-2Sn-4Zn-2Mo alloy used for exhaust valves. Using titanium alloys for automotive valves not only reduces weight and extends service life, but also provides increased reliability and fuel savings.
2. Connecting rods.
Using titanium alloys rods to manufacture connecting rods is the most effective way to reduce engine weight and significantly improve performance. The primary material used for connecting rods is Ti-6Al-4V, with other materials such as Ti-4Al-2Si-4Mn and Ti-7Al-4Mo also under development.
3. Crankshafts and other engine components.
Japan is currently trial-producing a Ti-5Al-2Cr-Fe alloy crankshaft, but this crankshaft requires anti-adhesion treatment and has not yet been commercialized. Other engine components, such as rocker arms, valve springs, and connecting rod lower bolts, can also be made from Ti-6Al-4V alloy.
4. Other components.
Bolts, nuts, and other connectors on automobiles, as well as transmission components like clutch discs and pressure plates, can all be made from titanium alloys. Compared to steel housings, titanium alloy clutch housings made using rotational molding can significantly reduce impact damage to the flywheel.
