GRCop-42 Powder for Additive Manufacturing
MET GRCop-42 is a dispersion strengthened copper alloy with high strength and a good resistivity against low cycle fatigue (LCF). With a conductivity reaching up to 75% of IACS, CuCrNb-alloys were originally designed for use in high heat flux applications, like for example in combustion chambers and nozzles, and therefore offer high oxidation resistance in harsh environment.
