EN 12164 Grade CuTeP R250 – Premium Low‑Alloy Copper Alloy for Precision Machining
CuTeP, mat. No CW118C, is counted among unhardenable, low alloyed copper alloys. To the comparable make CuTeP, mat. No 2.1546, acc. to DIN 17666 : 1983-12 applies: A strength increase is achievable only by cold forming. CuTeP is applicated as free-cutting alloy due to its favorable machinability. The alloy shows a higher temperature for removal of workhardening (350°C) compared to pure copper. CuTeP shows roughly the same electrical conductivity and corrosion resistance as copper. Processing properties: hot forming: very good cold forming: good machinability: very good soft and hard soldering: good gas shielded welding: good burnishing: good Application: In electronics and electrical engineering, e.g. for small parts such as diode bases and transistors. For welding torch nozzles, screws, nuts, parts for screw connections and fitting components.
