Electrical conductors of aluminum-based alloys and process for the manufacture thereof

In a process for the production of a wire by the sequential steps of continuously casting and rolling of a bar of an aluminum-silicon alloy consisting of by weight from 0.30 to 0.80% of Mg, from 0.30 to 0.70% of Si, from 0.15 to 0.35% of Fe, less than 0.20% of Cu, and the remainder of aluminum and the usual impurities, said rolling being carried out at a temperature of between 400.degree. and 500.degree. C and drawing the rolled bar into wire, the improvement comprising immediately after drawing rapidly cooling said rolled bar to a temperature below 150.degree. C, tepid drawing at a temperature of from about 110.degree. C to about 180.degree. C with an elongation of at least 350%, followed by artifically aging at a temperature between about 130.degree. C and about 240.degree. C wherein the ultimate tensile strength of the wire is about 37 kg/mm.sup.2 to about 41 kg/mm.sup.2.
