High Copper Alloys CuTeP (CW118C)

CuTeP is free-machining copper. The small tellurium addition makes the material excellent to machine without noticeably reducing conductivity. CuTeP conducts nearly as well as pure copper, yet turns and mills many times faster. Under EN it is designated CW118C, the earlier material number is 2.1546.

We supply CuTeP as round bars and hexagonal bars ex stock. Cut to your dimensions, no minimum order.
