Description

CuZr, mat. No CW120C, is counted among hardenable, low alloyed copper alloys. To the comparable make CuZr, mat. No 2.1580, acc. to DIN 17666 : 1983-12 applies: The strength properties of CuZr are not as favorable as for CuCrZr but it very well meets high requirements to tempering strength and creep strength at preferably high electric conductivity.Temperature for removal of workhardening approximates 525°C. Processing properties: hot and cold forming: good machinability: moderately soft soldering: moderately hard soldering: moderately gas shielded welding: moderately burnishing: good Application: For commutator lamellae of high strains, rotor windings in high loaded electric motors, diode bases, resistance welding electrodes as well as for electronic calculators.
