High purity aluminum alloy conductor for use at ultra low temperatures
Abstract
The present invention concerns an aluminum alloy conductor of a cryostatic stabilizer for use at ultra low temperatures of 30° K. or lower which is provided on and around a superconductor. The aluminum alloy conductor is made of 6 to 200 weight ppm of at least one element selected from the group of metallic and semimetallic effective elements consisting of B, Ca, Ce, Ga, Y, Yb and Th, and aluminum and inevitable impurities. The aluminum alloy conductor is obtained by adding at least one of these elements into a high purity aluminum whose purity is at least 99.98 wt. %. The aluminum alloy conductor has a 0.2% proof strength of not greater than 2.6 Kg/mm2.
