The material of the engine cylinder liners is generally ductile iron and alloy cast iron.
The material requires hardness above HB200 and tensile strength not less than 200MP, so that it will have good wear resistance, corrosion resistance and high temperature resistance.
Alloy cast iron cylinder liners:
Alloy cast iron cylinder liners are generally suitable for large engine units or engineering machinery with high temperature, high pressure, overload and extremely harsh conditions.
Ductile iron cylinder liners:
If it is a general machine tool or automobile engine, you can choose a ductile cast iron cylinder liner, which has the following advantages:
