Cu is the basis.
According to GOST 492-2006, the total mass fraction of impurities is ≤ 0.70%. 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, the mass fraction of lead is allowed to be ≤ 0.050%.
