<p>This disclosure relates to a method of continuously preparing a heat-resistant aluminum base alloy electrical conductor that has a minimum electrical conductivity of sixty-one percent (61%) IACS, improved properties of ultimate tensile strength, yield strength and elongation as compared with conventionally-prepared aluminum alloy electrical conductors, and superior thermal stability to continously-processed aluminum alloy electrical conductors. The conductor is prepared from an alloy melt containing from 0.30 to 1.30 weight percent iron, from 0.20 to 1.60 weight percent cobalt, from 0.48 to 0.88 weight percent silicon with the balance of aluminum containing trace elements selected from the group consisting of copper, manganese, magnesium, titanium, vanadium and zinc wherein the individual concentrations of said trace elements do not exceed 0.05 weight percent and the total concentration of said elements does not exceed 0.15 weight percent.</p> |
