AMPCO® 22: High-Performance Duplex Castings for Superior Hardness & Wear Resistance
AMPCO® 22 is a duplex structure alloy of approx. 50 % of each phase - gamma 2 and beta. It is remarkable because of its hardness, its excellent compression and wear resistance and by its sliding properties. As the elongation of the material is very low, thin sections should be avoided and the material should be well backed up.
