The use of aluminum as a replacement for copper would solve both the cost and the materials shortage problems, if a high strength aluminum alloy could be developed - provided the alloy had a resistance ratio ( rho 273K/ rho 4. 2K) equivalent to that of OFHC copper. This paper presents an assessment of the possibilities of developing such an alloy. The factors which influence yield strength and resistivity are outlined and a series of experiments are described. These experiments, conducted on dilute aluminum - gold alloys describe the process by which optimization of strength and resistivity can be achieved.
