Abstract: A hybrid conductor comprising a core section of CCA wire strands and at least one surrounding outer layer of high strength copper alloy of at least 60 ksi and preferably 80 ksi tensile strength, at least 85% IACS conductivity and at least 6% elongation.
Abstract: A copper base alloy achieves a breakthrough electrical conductor product of strength, flexure and conductivity of minimal inverse in relationship of at least 85% IACS electrical conductivity while providing an 80 to 85 ksi tensile strength, an increase of at least 33% in strength compared to prior art and is made from an alloy containing 0.2-0.5 w/o chromium, 0.02-0.20 w/o silver and 0.04-0.16 w/o of a third metallic component selected from tin, magnesium and tin/magnesium together.
