COPPER ALLOY

摘要

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.
