GOST 2208-2007 ≤0.02 ≤0.5 57-60 Rest ≤0.3 ≤0.01 0.8-1.9 ≤0.003
Cu is the basis.
According to GOST 15527-2004, GOST 2060-2006, GOST 2208-2007, the sum of other elements should be ≤ 0.750%. The total mass fraction of tin and silicon should not be more than 0.50%. In brass, the mass fraction of nickel is allowed up to 1.0% due to the mass fraction of copper, which is not taken into account in the sum of other impurities.
