Zn is the basis.
According to GOST 17711-93 and OST 5P.9209-82, the total amount of impurities should be ≤ 1.70%. Impurities not specified are taken into account in the total amount of impurities. The mass fraction of nickel in brass is allowed at the expense of copper and is not included in the sum of impurities. In the brass used for casting propellers, the mass fraction of copper should be 55.0-58.0%, aluminum - no more than 0.80%, lead - no more than 0.30%.
