use of aluminum alloy for the manufacture of electrically conductive objects with increased warmfestigkeit

摘要

Disclosed in the appended specification and claims are a high tensile strength aluminum alloy having high elongation and a minimum conductivity of about 60.0 percent IACS consisting of from about 0.08 to about 0.90 weight percent silicon, from about 0.30 to about 1.30 weight percent iron, from about 0.20 to about 1.60 weight percent cobalt and from about 96.20 to about 99.02 weight percent aluminum and a method of producing the alloy comprising the steps of alloying the recited elements, continuously casting the alloy into a bar, hot-rolling the bar substantially as cast into a continuous rod, cold drawing the continuous rod into a wire without intermediate anneals and annealing or partially annealing the wire.
