Abstract
The invention relates to a copper-zinc alloy, consisting of (in wt %): from 28.0 to 36.0% Zn, from 0.5 to 2.3% Si, from 1.5 to 2.5% Mn, from 0.2 to 3.0% Ni, from 0.5 to 1.5% Al, from 0.1 to 1.0% Fe, optionally also up to at most 0.1% Pb, optionally also up to at most 0.2% Sn, optionally also up, to at most 0.1% P, optionally also up to 0.08% S, remainder Cu and inevitable impurities, with mixed silicides of iron-nickel-manganese incorporated in the matrix.
