Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country VDA 231-106 classification
2.1010 (DIN 17662 : 1974-04) CuSn2 2.1010 DIN 17662 : 1974-04 DIN 17662 : 1974-04 replaced by DIN 17662 : 1983-12 Replaced Germany 3.2 1)
1) Remark: The properties of the CuSn wrought alloys are mainly influenced by the Sn-content. The tensile strength, the yield strength and the hardness will increase and the elongation decrease with increasing cold forming rate. The strength type F26 is reachable for this grade. The electric conductivity and the heat conductivity of this grade are lower than the values of pure Cu. The corrosion resistance is very good, especially to atmospheric influences, sea water, sulphite lye, carbonated and salted mine water. The alloys are resistant to stress corrosion Processing properties: Hot forming: good Cold forming: very good Cutting: mid Brazing: god Soft soldering: very good Gas-shielded welding: good Polishing: good Application: mechanical engineering, ship building, automotive engineering, chemical industry, electrical engineering, civil engineering, mining
