Abstract (en)
[origin: EP1217085A1] The invention relates to chemical compositions of alloys, particularly naturally hard semi-finished product alloys which should be used in said form as material for semi-finished products. The invention also relates to a naturally hard aluminium alloy for semi-finished product structures which is made of magnesium, titanium, beryllium, zircon, scandium and cerium and additionally manganese, copper, zinc and an element group containing iron and silicon, whereby the ratio of iron to the silicon ranges between 1 and 5. The composition of the aluminium alloy is (in wt. %): magnesium 5.0-5.6; titanium 0.01-0.05; beryllium 0.0001-0.005; zircon 0.05-0.15; scandium 0.18-0.30; cerium 0.001-0.004; manganese 0.05-0.18; iron 0.05-0.18; zinc 0.05-0.15; the element group containing iron and silicon 0.04-0.24 and the rest being aluminium.
