Abstract
A process for making aluminum alloy conductor wire having an electrical conductivity of at least 60.0% IACS which involves processing an alloy containing from 0.04 to 1.0% by weight iron, from 0.02 to 0.2% by weight silicon, from 0.1 to 1.0% by weight copper, from 0.001 to 0.2% by weight boron, balance essentially aluminum and processing said alloy without a final redraw step into wire. The process preferably includes hot working from at least approximately 900.degree. F. without reheating to form the redraw rod. This hot working is performed in order to allow the wire produced from this process to meet the desired properties at the final gages, such properties including high electrical conductivity under rapid annealing conditions.
