Technical requirements of piston parts

1. must have sufficient strength and stiffness, light weight, light weight, to ensure minimal inertia.
2. good thermal conductivity, high temperature, high pressure, corrosion, there is sufficient thermal capacity, small heating area.
3. the coefficient of friction between piston and piston walls should be small.
4. when the temperature changes, smaller changes in size, shape, and to keep a minimum clearance between the cylinder walls.
5. small thermal expansion coefficient, the proportion of small and has good wear resistance and thermal strength.
