Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Successor VDA 231-106 classification
CW120C (DIN EN 12163 : 1998-04) CuZr CW120C DIN EN 12163 : 1998-04 DIN EN 12163 : 1998-04 replaced by DIN EN 12163 : 2011-08 Replaced Germany CuZr 3.2 1)
1) Remark: 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.
