Abstract (en)
[origin: WO03054243A1] The invention relates to a component or semi-finished piece made from a hot-form aluminium alloy of the following composition in wt. %: silicon 0.9 - 1.3, magnesium 0.7 - 1.2, manganese 0.5 - 1.0, copper less than 0.1, iron less than 0.5, chromium less than 0.25, titanium less than 0.1, zinc less than 0.2, zirconium and/or hafnium 0.05 - 0.2 and further unavoidable impurities, whereby the total amount of chromium and manganese and zirconium and/or hafnium is at least 0.4 by weight. The component is characterised in that aluminium/silicon mixed crystals are present in addition to magnesium silicide precipitates.
