1. Method of preparing an aluminum base alloy conductor having a minimum conductivity of at least 57% IACS comprising the steps of:

  • A. alloying 0.60% Nickel, 0.30% Niobium, 0.18% Tantalum, and the remainder Aluminum with associated trace elements;

    B. casting the alloy in a moving mold formed between a groove in the periphery of a rotating casting wheel and a metal belt lying adjacent said groove for a portion of its length;

    C. hot rolling the cast alloy substantially immediately after casting while the cast alloy is in substantially that condition as cast to form a continuous rod;

    said aluminum alloy conductor having a tensile strength of at least 12,000 psi, and a yield strength of at least 8,000 psi when measured as a fully annealed wire, and has good thermal stability characteristics.
