Description
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. This alloy is lead and beryllium free (<0,01%).
This alloy is melted and produced by MATERION in the USA. Each batch is delivered with its original certificate of conformity to warranty a full traceability.
Main applications
With a combination of high strength and thermal conductivity, and friction, wear and corrosion resistance, PerforMet alloy withstands higher pressures and temperatures in high-power-density engines. Combined, these benefits can increase power and torque while lowering fuel consumption. 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.
Metallurgy
The alloy is usually mill hardened.
Machinability
This alloy can be easily machined.
Corrosion resistance
This alloy exhibits a high corrosion resistance to seawater or industrial atmosphere. This alloy is immune to hydrogen embrittlement.
