The piston ring in our piston set is characerized by strong ablities to resist abrasion and adhesive abrasion

our piston  is made of high quality aluminum alloy (ADC12)through precision centre (CNC)therefore,it has the advantage of strong heat stability(strength>=69Mpa,under 3000C high temperature while tensile strength is >=196.12Mpa under normal temperature.low coefficient of expasion(<=0..03D%) and super-strong hardness (95-130HBC).
