Abstract
It is common practice to use pure copper as the material of choice in applications requiring adequate strength and high electrical conductivity (EC). However, the overwhelming increase in the cost and worldwide demand for copper is becoming a major concern. As the move towards electrification throughout the world is occurring, so is a parallel move to make aluminum (Al) and Al alloys suitable as a replacement for copper. To make this goal a reality, exploration into enhancements in the strength and EC of high conductivity Al alloys is necessary. This study compiles strength and EC data for current Al powder metallurgy (PM) alloys to better understand existing data and target future research. Also highlighted are reviews of completed research projects, including studies relating to liquid metallurgy, by industry professionals and academia, noting both shortcomings and successes.
