Piston is one of the most important parts of engine. It can bear air pressure drive crankshaft by transmitting from piston pin to connecting rod. When engine is at work, the piston bears high temperature, high pressure, heat load and mechanical load. Piston, as a vital component for transmitting energy of automotive engine, has special requirements on its materials: low density, light weight, good thermal conductivity, and low thermal expansion coefficient; sufficient high temperature strength, wear resistance and corrosion resistance, good dimension stability. Additionally, it also embraced the feature that easy to manufacture and low-cost.

Piston can be applied in cast iron, forged steel, cast steel and aluminum alloys and other materials. Among them, aluminum alloys has been widely used in piston manufacturing by its merits of lightweight, good thermal conductivity, lower coefficient of thermal expansion and other features.
