Dilute aluminum alloys containing less than one weight percent solute were examined for changes in the resistance ratio and yield strength as a function of aging treatment. The elemental solutes Au and Co and combinations of Co, Ni and Sb serve as effect strengthening agents. A figure of merit defined as the ratio of yield strength to resistivity at 4. 2 K has been developed. Other material characteristics such as grain size and dislocation density have been considered in light of their contribution.
