Copper-Alum Composite Material

Copper-aluminum composite material is a laminated bimetallic material where pure copper and aluminum alloy are tightly bonded at the atomic level via metallurgical composite processes. It is not merely laminated or glued together, and a stable diffusion layer forms at the bonding interface, preventing delamination during bending, stamping and heat treatment.
