Titanium is used as a variety of auto parts, and its main advantages are:
Low density: it can minimize not only the weight of the vehicle, but also the inertia of the fast moving elements.
High specific strength: titanium has the highest specific strength of any metal substance and may be employed as a load-bearing component.
Small elastic modulus: only half that of steel, and fatigue strength, making it appropriate for springs.
Good heat resistance: can work at 200-650°C for an extended period of time, making it suited for high temperature components.
Steel and aluminum have a low coefficient of thermal expansion, making them ideal for engine valves and other components.
Excellent corrosion resistance: better than aluminum, magnesium, and stainless steel, it can withstand the corrosion of air, rain, anti-freezing road moisture, and high temperature exhaust gas containing hydrogen sulfide, making it suitable for tail nozzles and other parts exposed to harsh environments.
Good freezing resistance: it will not generate low temperature brittleness in a -100 °C environment.
Good formability: stamping, hot forging, powder metallurgy, precision casting, and other technologies may be used to manufacture varied forms of components.
Ornamental good: by oxidation processing, a vivid range of decorative materials may be formed.
