CW453K (DIN EN 12163 : 1998-04) CuSn8 CW453K DIN EN 12163 : 1998-04 DIN EN 12163 : 1998-04 replaced by DIN EN 12163 : 2011-08 Replaced Germany CuSn8 3.2 1)
1) Remark: CuSn8, mat. No. CW453K, is comparable to the DIN-make CuSn8, mat. No. 2.1030, acc. to DIN 17662 : 1983-12. Properties of the CuSn-alloy are predominantly determined by the tin-content. Tensile strength, yield point and hardness increase according to the rising cold forming grade, elongation after fracture decreases. Electrical and thermal conductivity are lower than for pure copper. Very high resistance to corrosion, particularly to atmospheric influences, seawater, sulfite liquor, carbonated and salted mine water. The alloys are stress corrosion-proof. Processing properties: warm forming: medium cold forming: very good machinability: medium hard soldering: good soft soldering: good gas shielded welding: good burnishing: good Application: For friction elements, especially for thin-walled friction-bearing bushings and sliding strips as well as for beater bars. Increased abrasion and corrosion resistance compared to CuSn6. 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)
