Standards

Name Code Standards
Non-ferrous metals, including rare metals, and their alloys В51 GOST 28873-90, GOST 492-2006

Chemical composition

Standard Mn Fe Cu Zn Pb Ni+Co
GOST 492-2006 ≤0.5 ≤0.3 60-64 The rest ≤0.03 17-19
Cu is the basis.
According to GOST 492-2006, the total mass fraction of impurities is ≤ 0.60%. In the alloy, the mass fraction of cobalt ≤ 0.50% is allowed due to the mass fraction of Ni + Co, which is not taken into account in the total amount of impurities. The mass fraction of cobalt exceeding 0.50% is taken into account in the total amount of impurities. In the alloy, in agreement with the consumer, it is possible to determine the mass fraction of silicon, magnesium, arsenic, bismuth, phosphorus, tin, antimony.

Technological properties
