Abstract
Official abstract text for this publication.
The invention relates to a copper-nickel-zinc alloy with the following composition in weight percentages: 46.0 to 51.0% Cu, 8.0 to 11.0% Ni, 0.2 to 0.6% Mn, 0.05 to 0.5% Si, up to 0.8% of each of Fe and/or Co, the sum of the Fe content and double the Co content equaling at least 0.1 wt. %, residual Zn, and unavoidable impurities, wherein nickel-, iron-, and manganese-containing and/or nickel-, cobalt-, and manganese-containing mixed silicides are embedded into a microstructure consisting of α- and β-phases as spherical or ellipsoidal particles. The invention further relates to uses of a copper-nickel-zinc alloy according to the invention.
First claim
Opening claim text (preview).
1 . A copper-nickel-zinc alloy having the following composition [in % by weight]: Cu from 46.0 to 51.0%, Ni from 8.0 to 11.0%, Mn from 0.2 to 0.6%, Si from 0.05 to 0.5%, Fe and/or Co in each case up to 0.8%, where the sum of Fe content and twice the Co content is at least 0.1%, balance Zn and unavoidable impurities, wherein nickel-, iron- and manganese-containing and/or nickel-, cobalt- and manganese-containing mixed silicides are embedded as spherical or ellipsoidal particles in a microstructure consisting of α and β phase. 2 . The copper-nickel-zinc alloy as claimed in claim 1 having the following composition [in % by weight]: Cu from 47.5 to 49.5%, Ni from 8.0 to 10.0%, Mn from 0.2 to 0.6%, Si from 0.05 to 0.4%, Fe from 0.2 to 0.8%, optionally up to 0.8% of Co, balance Zn and unavoidable impurities, wherein nickel-, iron- and manganese-containing mixed silicides are embedded as spherical or ellipsoidal particles in a microstructure consisting of a and p phase. 3 . The copper-nickel-zinc alloy as claimed in claim 1 having the following composition [in % by weight]: Cu from 47.5 to 49.5%, Ni from 8.0 to 10.0%, Mn from 0.2 to 0.6%, Si from 0.05 to 0.4%, Co from 0.1 to 0.8%, optionally up to 0.8% of Fe, balance Zn and unavoidable impurities, wherein nickel-, cobalt- and manganese-containing mixed silicides are embedded as spherical or ellipsoidal particles in a microstructure consisting of α and β phase. 4 . The use of a copper-nickel-zinc alloy as claimed in claim 1 for producing consumer goods having demanding requirements in terms of the surface quality. 5 . The use of a copper-nickel-zinc alloy as claimed in claim 1 for producing keys, locks, plug connectors or points for ballpoint pens.
