The present invention relates to the chemical composition of alloys, in particular naturally hard semifinished-material alloys, which are intended to be used in this form as material for semifinished materials. Proposed is a naturally hard aluminum alloy for semifinished materials which, in addition to magnesium, titanium, beryllium, zirconium, scandium, and cerium, is also made of manganese, copper, zinc, and an element group containing iron and silicon, the ratio of iron to silicon being in the range of 1 to 5.
La présente invention concerne des compositions chimiques d'alliages, notamment d'alliages de demi-produits à dureté naturelle, lesdits alliages entrant dans la composition de demi-produits sous cette forme. La présente invention concerne en particulier un alliage d'aluminium à dureté naturelle destiné à des structures de demi-produits. Ledit alliage d'aluminium contient en % en poids: magnésium (5,0-5,6) ; titane (0,01-0,05); béryllium (0,0001-0,005); zircon (0,05-0,15); scandium (0,18-0,30); cérium (0,001-0,004); manganèse (0,05-0,18); cuivre (0,05-0,18); zinc (0,05-0,15); un groupe d'éléments contenant fer et silicium (0,04-0,24), le rapport entre fer et silicium étant de 1 à 5 ; et, un reste d'aluminium.
