Alloys or metal-composites with volumetric electrical conductivity greater than that of their substrate metal are defined as ultra-conductive materials (UCMs). With the recent interest in grid efficiency improvement and vehicle electrification, UCMs are anticipated to play a major role in developing energy efficient solutions such as high conductivity cables and busbars, and high-performance interconnects. While ultra-conductive behavior has been documented at sub-micron scales, it has been challenging to scale up the technology using traditional manufacturing processes. This presentation will focus on recent advances made in improving the electrical performance of aluminum alloys using a low-cost, high throughput solid phase processing approach, hot-extrusion alloying. Effects of process parameters and base alloy compositions on UCM performance will be discussed. Electrical and mechanical behavior of UCMs as a function of graphene-like additive content will be explored. Finally, potential for incorporating UCMs in existing technologies for the development of energy-efficient solutions will be examined.
