Material Description

Material Number Material Name Material Number (single) Standard Standard Status Country VDA 231-106 classification
2.0771 (DIN 17663 : 1983-12) CuNi7Zn39Mn5Pb3 2.0771 DIN 17663 : 1983-12 Withdrawn without replacement Germany 3.2 1)
1) Remark: CuNi7Zn39Mn5Pb3 is a alloy of high strength. It has a good machinability. The conductivity is low. Because of the Zn content lower resistance to corrosion for aggressive media. Processing properties: Hot forming: good Cold forming: poor Machinability: very well Brazing: very well Soldering: good Gas-shielded welding: medium Polishability: good Application: optical industry, fine mechanics
