Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor Successor VDA 231-106 classification
CW102C (DIN EN 12164 : 2011-08) CuBe2Pb CW102C DIN EN 12164 : 2011-08 DIN EN 12164 : 2011-08 replaced by DIN EN 12164 : 2016-11 Replaced Germany CuBe2Pb CuBe2Pb 3.2 1)
1) Remark: CuBe2Pb, mat. No CW102C, is a hardenable, low alloyed copper alloy. The alloy shows a very high tensile strength and increased temperature resistance and mean electrical and favorable thermal conductivity. Processing properties: hot and cold forming: good machinability: moderately hard and soft soldering: good gas shielded welding: good burnishing: good Application: For all types of springs, membranes, wear resistant parts, as well as for non-sparking tools.
