Abstract
The invention relates to an aluminium alloy for an anti-friction element containing respectively, as a % by weight, 4.2% to 4.8% Zn, 3.0% to 7.0% Si, 0.8% to 1.2% Cu, 0.7% to 1.3% Pb, 0.12% to 0.18% Mg, 0% to 0.3% Mn and 0% to 0.2% Ni. Also incorporated, based on % by weight, are 0.05% to 0.1% Zr, 0% to 0.05% Ti, 0% to 0.4% Fe, 0% to 0.2% Sn. The rest is formed by Al with the usual incidental impurities depending on the melt.
