<p>The present invention relates to a die-casting brass alloy having a dezincification resistance, which is lower than 100 νm for a separate value according to British Standard BS 2872 in a die-casting condition (i.e. without a subsequent phase transforming heat treatment). The alloy according to the invention is characterized by the following composition: Cu: 63,6 weight-%; Pb: 1,8 weight-%; Si: 0,73 weight-%; Al: 0,07 weight-%; As: 0,06 weight-%; Ni: 0,2 weight-%; Sn: 0,3 weight-%; Fe: 0,25 weight-%; B: 8 ppm. Other impurities: max.0,3 weight-%, Zn: remainder.</p> |
