Abstract (en)
[origin: WO2013023717A2] The invention relates to a copper alloy that has been subjected to a thermo-mechanical treatment, composed of (in wt%) 15.5 to 36.0% Zn, 0.3 to 3.0% Sn, 0.1 to 1.5% Fe, optionally also 0.001 to 0.4% P, optionally also 0.01 to 0.1% Al, optionally also 0.01 to 0.03% Ag, Mg, Zr, In, Co, Cr, Ti, Mn, optionally also 0.05 to 0.5% Ni, the remainder copper and unavoidable contaminants, wherein the microstructure of the alloy is characterized in that the proportions of the main texture layers are at least 10 vl% copper layer, at least 10 vl% S/R layer, at least 5 vl% brass layer, at least 2 vl% Goss layer, at least 2 vl% 22RD-cube layer, at least 0.5 vl% cube layer, and finely distributed iron-containing particles are contained in the alloy matrix.
