Standards
Chemical composition
Cu is the basis.
According to GOST 18175-78, the total mass fraction of normalized impurities is ≤ 1.70%. As agreed by the manufacturer with the consumer, the content of impurities of arsenic and antimony can be normalized. The mass fraction of nickel is allowed up to 0.50% without taking it into account in the total amount of impurities.
