Cu is the basis.
The total fraction of impurities in the OST 1 90054-72 (elements with a content ≤) is 0.8%. Impurities that are not regulated by the table are included in the total amount of impurities.
According to GOST 613-79, the total content of impurities should be ≤ 0.90%. Impurities not regulated by the standard are included in the total amount of impurities. The mass fraction of nickel due to copper and the amount of impurities is not included. The mass fraction of phosphorus, as agreed by the manufacturer with the consumer, is allowed up to 1.00%, and in this case the total amount of impurities is not included.
