| 摘要 |
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.
