Cu is the basis.
According to GOST R 51573-2000, GOST 15527-2004 the sum of other elements should be ≤ 0.30%. In brass, the mass fraction of nickel is allowed up to 0.50% due to the mass fraction of copper, which is not taken into account in the sum of other impurities. In brass, the total mass fraction of phosphorus and arsenic should not be more than 0.040%.
