4032 alloy, more silicon contained compare to 2618 alloy, lower noise, higher tensile strength, lower thermal expansion coefficient.

High precision, 0.001 mm tolerance for pin hole, 0.005 mm tolerance for diameter, clearance between cylinder to skirt is 0.04-0.06 mm.

Features:

1, Completely Phosphate Coated, increase Oil Adhesion for better lubrication.
