PerforMet™ alloy from Materion is a nickel-silicide strengthened copper alloy with high strength and high thermal conductivity. It resists mechanical wear, corrosion and galling and has a low coefficient of friction when mated to other metals. PerforMet alloy retains its strength at elevated temperatures. It is non-magnetic and easily machined. Applications include valve seats, valve guides, piston rings and plain bearings, where PerforMet alloy provides long life while efficiently removing heat from critical engine components.
