Hexagon barsHigh Copper Alloys CuCr1Zr (CW106C)
CuCr1Zr is the copper alloy for components that carry current and bear mechanical load at the same time. At medium strength the material reaches a very high electrical conductivity of around 79 percent IACS, that is about 46 MS/m, and a high softening temperature with correspondingly long service life. Under EN it is designated CW106C, the earlier material number is 2.1293.
We supply CuCr1Zr as round bars, flat bars, hexagonal bars and sheets ex stock. Cut to your dimensions, no minimum order.
