Cu is the basis.
According to GOST 10092-2006, a cobalt mass fraction of 0.50% is allowed due to the mass fraction of nickel + cobalt, which is not taken into account in the total amount of impurities. It is allowed to determine the mass fraction of the tin impurity. The sum of impurities is ≤ 0.6%. An impurity should be considered an element that has only the maximum limit of its content.
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 tin.
