STRUCTURAL ALUMINIUM ALLOY WITH INCREASED ELECTRICAL RESISTIVITY.

An aluminium alloy for structures with increased electrical resistivity consisting essentially of: 1. 0 approximately 5. 0% of Li; one or more elements selected from the group consisting of 0. 05 approximately 0. 20% Ti, 0. 05 approximately 0. 40% of Cr, 0. 05 approximately 0. 30% of Zr, 0. 05 approximately 0. 35% of V and 0. 05 approximately 0. 30% of W; and the balance being aluminium and impurities. 0. 05 approximately 8. 0% of Mg, 0. 05 approximately 5. 0% of Cu and up to 5. 0% of Mn can be included to improve strength and electrical resistivity. The alloy has, at least, the tensile strength of 20kgf/mm**2 and the electrical resistivity of 8. 6 mu OMEGA cm, and can be applied as structural materials in the field subject to a large magnetic force such as linear motor vehicles and nuclear fusion reactors.
