Abstract: A method for producing a die-cast component and a die-cast component that is produced therewith. According to the invention, an outstanding punch riveting suitability is achieved if the die-cast component has a temperable aluminum alloy with the following alloying components: from 5.0 to 9.0 wt % silicon (Si), from 0.25 to 0.5 wt % magnesium (Mg), and residual aluminum as well as inevitable production-related impurities, containing at most 0.05 wt % of each and at most 0.15 wt % collectively, wherein the die-cast component has a yield strength (Rp0.2) of greater than 190 MPa and an elongation at break (A5) of greater than or equal to 7% and the uniform elongation (Ag) and necking elongation (Az) satisfy the condition Az?Ag/2.

Abstract: A method for producing a sheet or strip from an aluminum alloy and a sheet, strip or molded part produced thereby are disclosed. A rough surface and stretcher strain marks can be avoided if the cold-rolled sheet or strip with a particular composition and microstructure is subjected to a heat treatment with a recrystallization annealing and a subsequent accelerated cooling.

Abstract: A hardenable Al—Mg—Si-based aluminum alloy is shown. In order to provide a recycling-friendly, storage-stable and particularly thermosetting aluminum alloy, it is proposed that this aluminum alloy should contain from 0.6 to 1% by weight of magnesium (Mg), from 0.2 to 0.7% by weight of silicon (Si), from 0.16 to 0.7% by weight of iron (Fe), from 0.05 to 0.4% by weight of copper (Cu), a maximum of 0.15% by weight of manganese (Mn), a maximum of 0.35% by weight of chromium (Cr), a maximum of 0.2% by weight of zirconium (Zr), a maximum of 0.25% by weight of zinc (Zn), a maximum of 0.15% by weight of titanium (Ti), 0.005 to 0.075% by weight of tin (Sn) and/or indium (In), and the remainder aluminum and production-related unavoidable impurities, wherein the ratio of the weight percentages of Si/Fe is less than 2.5 and the content of Si is determined according to the equation wt. % Si=A+[0.3*(wt. % Fe)], with the parameter A being in the range of 0.17 to 0.4% by weight.

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.
