Description

CuSP, mat. No CW114C, is counted among unhardenable, low alloyed copper alloys. To the comparable make CuSP, mat. No 2.1498, acc. to DIN 17666 : 1983-12 applies: A strength increase is achievable only by cold forming. Already low S-contents increase the temperature for removal of workhardening to approx. 300°C. CuSP shows roughly the same electrical and thermal conductivity as pure copper. The corrosion resistance is equal to unalloyed copper. Processing properties: hot forming: moderately cold forming: good machinability: very good soft soldering: good hard soldering: moderately gas shielded welding: unfavorable burnishing: good Application: For screw machine parts and clamps in electronics, for nozzle, welding and cutting torches as well as for engine parts, valves and fittings.
