ABSTRACT:
An aluminum alloy electrical conductor having an electrical conductivity of at least fifty-seven percent (57%) based on the International Annealed Copper Standard and unexpected properties of increased bendability, creep resistance, fatigue resistance and thermal stability at a minimum standard elongation, when compared to conventional aluminum alloy conductors of the same tensile strength is described. The aluminum alloy conductors are produced by the addition of from about 0.10 weight percent to about 1.00 weight percent copper and up to about 0.10 weight percent iron to an alloy mass containing from about 98.70 weight percent to about 99.90 weight percent aluminum, and trace quantities of conventional impurities normally found within a commercial aluminum alloy.
