Cu is the basis.
According to GOST 613-79, the total content of impurities should be ≤ 1.30%. 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 sum of impurities is not included.
