摘要：This disclosure relates to a high tensile strength aluminum alloy electricalconductor that is manufactured by alloying at least one alloying element with moltenaluminum in sufficient proportion to yield intermetallic precipitates during subsequentsolidification 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 theonset of recovery such that there will be produced secondary intermetallic precipitatescorresponding to the primary precipitates which come out of solution during casting,whereby both the primary and secondary precipitates act to pin dislocation sites betweenadjacent subgrain boundaries in the aluminum matrix thereby increasing the ultimatetensile strength and yield strength of the conductor.
