    GOST 15527-2004 ≤0.01 ≤0.1 72-75 Rest ≤0.005 2.4-3 ≤0.002
    Cu is the basis.
    According to GOST 15527-2004 the sum of other elements should be ≤ 0,25%. 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.
