CW008A (DIN EN 12165 : 2011-08) CW008A DIN EN 12165 : 2011-08 DIN EN 12165 : 2011-08 replaced by DIN EN 12165 : 2016-11 Replaced Germany Cu-OF Cu-OF 3.2 1)
1) Remark: Cu-OF, mat. No CW008A, is a copper free of oxygen and deoxidation agents. The material is hydrogen resistant and shows very high thermal and electrical conductivity. Tensile strength and Brinell hardness are increasable by cold forming. Processing properties: hot forming: very good cold forming: very good machinability: unfavorable hard soldering: good soft soldering: very good gas-shielded welding: good burnishing: very good Application: Preferred application in electrical engineering, electronics, vacuum technology as well as for production of all types of semifinished parts when highest electrical conductivity is required. For the electrolytically tinned strip the coatings (Sn bright, Sn matt, Sn fuzed, SnPb) are listed by the application (better solderability, better corrosion resistance, reduction of the electrical contact resistance, better appearance) in the DIN EN 14436 : 2004-11 (Table 5)
