CW021A (DIN EN 12165 : 1998-04) CW021A DIN EN 12165 : 1998-04 DIN EN 12165 : 1998-04 replaced by DIN EN 12165 : 2011-08 Replaced Germany Cu-HCP 1)
1) Remark: Cu-DHP, mat. No CW021A, is a deoxidized copper with low phosphorus-content. To the comparable DIN-mark SF-Cu, mat. No 2.0070 acc. to DIN 1787: 1973-01 (precondition for the comparability: Cu-content min. 99,95%, deoxidation agent phosphorus) applies: The material is also available in a special quality free of steam stripping elements. This is very important for vacuum technology. Tensile strength and Brinell hardness are increasable by cold forming. SE-Cu is hydrogen resistant and shows the lowest thermal and electrical conductivity of the pure copper materials. Processing properties: hot forming: very good cold forming: very good machinability: unfavorable hard soldering: very good soft soldering: very good gas-shielded welding: good burnishing: good Application: Preferably application in electrical engineering, electronics. For production of all types of semifinished parts when high electrical conductivity is demanded as well as in vacuum technology and as cladding material.
