Abstract (en)

[origin: WO2022217338A1] The present disclosure concerns a foundry alloy suitable for casting operations which lack beryllium. The foundry alloy comprises, in weight percent, Mg (between about 1.0 and about 17.0), Fe (between about 0.5 and about 1.8), one of Ca (between about 0.003 and about 6.0) or Sr (between about 0.003 and about 2.5), optionally a grain refiner and the balance being aluminum and unavoidable impurities. The foundry alloy can be used in a process for making a cast aluminum product, for reducing Mg loss and/or dross generation during the casting operation.
