Material Description

Material Number	Material Name	Material Number (single)	Standard	Standard Status	Country	VDA 231-106 classification
2.0740 (DIN 17663 : 1983-12)	CuNi18Zn20	2.0740	DIN 17663 : 1983-12	Withdrawn without replacement	Germany	3.2	1)
1) Remark: CuNi18Zn20 is a alloy of high strength and hardness. The strength can be increased by cold forming. A strength of F38 to F62 can be reached. No embrittlement at lower temperatures. The conductivity is low. The alloy is non ferromagnetic. Better resistance to corrosion than pure Cu. Processing properties: Hot forming: medium Cold forming: very well Machinability: medium Brazing/Soldering: very well TIG-welding: very well Polishability: very well Application: in the electrical and electronical engineering for springs, contacts, membranes, for fine mechanics and apparatus engineering, food industry, musical instruments, frames for glasses, safety keys , in the civil engineering for wall panels, show cases, stair rails
