Estimating the term…
The invention refers to the metallurgy, in particular to non-heat-treatable electrical-grade aluminium alloys. The alloy contains, % wt: Fe up to 0.2, Si up to 0.08, Zr 0.05-0.11, Sc 0.01-0.03, Er and Yb in total or separately 0.02-0.15, inevitable impurities each not more than 0.01 and in total not more than 0.05 including V, Ti, Mn, Cr in total not more than 0.02, aluminium not less than 99.5. It structurally has nanodispersed precipitates with L12 crystalline structure of Al3Sc and Al3Zr phases, as well as Al3(Sc,Zr) and Al3(Sc,Zr,Er,Yb) multicomponent phases. The alloy also may contain Ce and Y in total or separately 0.05-0.3% wt. The alloy has high mechanical properties and high electrical conduction not less than 60% IACS.
Electrical-grade aluminium alloy containing iron, silicon, zirconium, scandium, and at least one element from the group of Er and Yb, with the following ratio of components, % wt:
