C172 Beryllium Copper Alloy Wire (CuBe2)
Download PDFBeryllium Copper alloys combine form-ability with very high strength properties when aged. Applications are in springs, connectors, switches and automotive parts. Special heat treating of the wire at the mill produces a “Mill Hardened” (HM) tempered Beryllium Copper wire which can then be formed and used without additional heat treatment.
