  • DIECASTING ALLOY BASED ON AL-SI, COMPRISING PARTICULARLY SECONDARY ALUMINUM
    Publication number: 20150098859
    Abstract: A diecasting alloy based on Al—Si is made of 6 to 12% by weight of silicon (Si), at least 0.3% by weight of iron (Fe), at least 0.25% by weight of manganese (Mn), at least 0.1% by weight of copper (Cu), 0.24 to 0.8% by weight of magnesium (Mg) and 0.40 to 1.5% by weight of zinc (Zn). The alloy also has 50 to 300 ppm of strontium (Sr) and/or 20 to 250 ppm of sodium (Na) and/or 20 to 350 ppm of antimony (Sb), and at least one of the following constituents: titanium (Ti) to an extent of not more than 0.2% by weight; not more than 0.3% by weight of zirconium; not more than 0.3% by weight of vanadium (V); and as the remainder aluminium and unavoidable impurities resulting from the production. The total content of Fe and Mn in the diecasting alloy together is not more than 1.5% by weight, the quotient of the percentages by weight of Fe and Mn is 0.35 to 1.5, and the quotient of the percentages by weight of Cu and Mg is 0.2 to 0.8.
