GOST 2208-2007 ≤0.01 ≤0.1 61-63 The rest 0.7-1.1 ≤0.005 ≤0.1 ≤0.002
Cu is the basis.
According to GOST 15527-2004, GOST 2060-2006, GOST 2208-2007, 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.
