Abstract
High-purity aluminum (99.999+% purity) is being used as a stabilizer material in many composite superconducting cables rather than copper. Since large superconducting energy storage devices require immense quantities of the stabilizer material, the more abundant high-purity aluminum is the only feasible choice for a stabilizer. Although aluminum compares favorably with copper for stabilizer use at 4.2 K because of its low density, low specific heat, and low resistivity, aluminum has a very low yield strength. †
