The results of annealing on the residual resistance ratio (RRR) of composite aluminum cryoconductor wire are presented. The independent variables of the study include the wire diameter, number of pure aluminum filaments, matrix alloy composition and manufacturing method. The dependent variables include annealing temperature, annealing time and cooling rate. This investigation was undertaken to determine the optimum post manufacturing heat treatment and to learn about the sensitivity of wire RRR to variations in the heat treatment schedule.
