Chemical composition

Standard Ni Fe Cu Al Zn Sn Pb
GOST 15527-2004 ≤0.4 ≤0.4 57-59 ≤0.1 Rest ≤0.3 1.5-2.5
Cu is the basis.
According to GOST 15527-2004 the sum of other elements should be ≤ 0,20%. 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.
