Abstract: The invention relates to a high temperature stability Al—Si—Cu casting alloy with an addition of Sn to improve ageing kinetics and mechanical properties. The alloy is suitable for gravity die casting and comprises 6 to 8 wt. % Si, 2 to 4 wt. % Cu, 0.03 to 0.09 wt. % Sn, 0.05 to 0.1 wt. % Ti, up to 0.2 wt. % Mn, up to 0.2 wt. % Fe, up to 0.03 wt. % Sr, grain refining element in the scale of 1 N kg/ton and unavoidable impurities up to 0.05 wt. %. The alloy may also contain one or more of the following elements: Mg max 0.25 wt. %, Zr max 0.2 wt. % and Hf max 0.5 wt. %. The addition of Sn leads to the finer and denser distribution of O?—Al2Cu precipitates, enhancing the mechanical properties and ageing kinetics of the alloy.

Abstract: The present invention relates to a castable heat resistant aluminium alloy for high temperature applications such as components in combustion engines, in particular for the manufacturing of highly loaded cylinder heads, he alloy comprises the following composition: .Si: 6.5-10 wt %.Mg: 0.25-0.35 wt %.Cu: 0.3-0.7 wt %.Hf: 0.025-0.55 wt % Optionally with the addition of: .Ti: 0-0.2 wt %.Zr: 0-0.3 wt %, the balance being made of Al and unavoidable impurities including Fe.

Abstract: Present invention relates to a method and means for producing moulded bodies of a metal foam (9), in particular an aluminium foam. The Method involves the use of mould (1) having a cavity (8) and at least one entrance opening (3). The mould id filled with a metal foam in a manner where the entrance opening of the mould is submerged into a metal melt (4) and the melt is caused to foam inside the mould (81) and fill its cavity (8).
