EN 12168 Grade CuTeP H080: High-Performance Copper Alloy for Superior 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.
