    Cu is the basis.
    The total proportion of impurities in the OST 1 90054-72 (elements with a content ≤) is 1.20%. Impurities that are not regulated by the table are included in the total amount of impurities.
    According to GOST 613-79 and OST 5P.9209-82, the total content of impurities should be ≤ 1.00%. Impurities not regulated by the standard are included in the total amount of impurities. The sum of impurities of silicon and aluminum should not exceed 0.020%. In bronze, not intended for casting parts operating under hydraulic pressure, the manufacturer's agreement with the consumer allows the mass fraction of aluminum to 0.050% and silicon - up to 0.050%. The mass fraction of nickel due to copper and the amount of impurities is not included. The mass fraction of lead, as agreed by the manufacturer with the consumer, is allowed up to 1.50%, in which case the total amount of impurities is not included. In bronze intended for welded structures, the mass fraction of lead should be no more than 0.050%.
