| 2.0790 (DIN 17663 : 1983-12) | CuNi18Zn19Pb1 | 2.0790 | DIN 17663 : 1983-12 | Withdrawn without replacement | Germany | 3.2 | 1) |
| 1) Remark: CuNi18Zn19Pb1 is a alloy of high strength. The strength can be increased by cold forming. A strength of F44 to F53 can be reached. No embrittlement at low temperatures. The conductivity is low. The alloy is non ferromagnetic. Better resistance to corrosion than pure Cu. The addition of Pb improve the machinability, the toughness and the cold formability are reducing. Processing properties: Hot forming: poor Cold forming: medium Machinability: good Brazing/Soldering: very well TIG-welding: medium Polishability: good Application: fine mechanics, apparatus engineering, electrics and electronic, ship building, civil engineering |
