Characteristics of composite electrical conductors for use at cryogenic temperatures Conference Paper uri icon


  • Non-superconducting composite aluminum cryoconductors compete favorably with composite superconductors for a variety of energy related applications. When cooled to 4.2K, cryoconductors can have effective resistances 1000 times less than their room temperature values. However, these cryoconductors are susceptible to strain degradation and can show dramatic increases in resistance if subjected to monotonic or cyclic plastic strains. Experimental results of cyclic strain experiments on composite aluminum cryoconductors at 4.2K are presented.
