ABSTRACT:
Aluminum conductor is made from direct chill cast (DC) ingot with improved conductivity and creep resistance by heating an aluminum-base alloy ingot containing not more than 0.40 wt. % and preferably not more than 0.30 wt. % Fe or a mixture of Mg, Ni or Zr with Fe to a temperature of 400.degree. to 600.degree. C., hot rolling the ingot in this temperature range and then further hot rolling at a reduced temperature range of 175.degree. to 325.degree. C.
