Characterization of Several Aluminum Alloys for Moderate-Strength High-Conductivity Applications
Practical superconductors are composite conductors containing filaments of superconducting material surrounded by a low-resistance normal metal called the stabilizer. The stabilizer is an electrical shunt when the superconductor goes normal and provides support for the superconducting filaments. Owing chiefly to considerations of electrical conductivity and superconductor compatibility, oxygen-free high-conductivity (OFHC) copper is the usual stabilizer material. Serious consideration of aluminum has arisen because of the increasing availability of high-purity material and the favorably low magnetoresistance effect. The factor most responsible for copper being favored over aluminum is inherent strength. Aluminum would be the choice for many applications if both metals had similar mechanical properties.
