Abstract
This disclosure relates to a high tensile strength aluminum alloy electrical conductor that is manufactured by alloying at least one alloying element with molten aluminum in sufficient proportion to yield intermetallic precipitates during subsequent solidification and thermomechanical processing. The conductor is in the form of a hard-drawn wire which is annealed at a temperature within the range corresponding to the onset of recovery such that there will be produced secondary intermetallic precipitates corresponding to the primary precipitates which come out of solution during casting, whereby both the primary and secondary precipitates act to pin dislocation sites between adjacent subgrain boundaries in the aluminum matrix thereby increasing the ultimate tensile strength and yield strength of the conductor.
