Effect of severe plastic deformation via co-extrusion on microstructure and electrical conductivity of copper clad aluminum conductors for e-motor applications

A square-shaped cross-section copper-clad aluminum (CCA) conductor was produced through co-extrusion at room temperature with an equivalent strain of 1.5. The bimetallic conductor retained a high electrical conductivity (EC) of 69.10% International Annealed Copper Standard (IACS), which was owed …
