Material Description

Material Number	Material Number (single)	Standard	Standard Status	Country
CW128C (DIN EN 50149 : 2013-02)	CW128C	DIN EN 50149 : 2013-02	Valid	Germany	1)
1) Remark: Low-alloy non heat-treatable copper-magnesium for railway applications for fixed installations of electric traction, e.g. grooved contact wires. Magnesium increases strength with little reduction in conductivity. CuMg alloys substitute CuCd alloys due to the toxicity of Cd.
