Alumina dispersion-strengthened copper alloy is a copper matrix alloyed copper matrices with dispersed, thermally stable, dislocation-clamped, submicron granules of Al2O3. Softening is not prominent, even with high temperature exposure. With exceptional strength retention, thermal and electrical conductivities are better than those of conventional alloys.

Alumina copper, also known as dispersed copper, dispersed aluminium copper, aluminium oxide copper, ceramic copper, aluminium copper, and dispersion-strengthened copper, has various manufacturing processes. The traditional alumina melting-casting method (also called powder mixing-sintering-extrusion) suffers from poor material performance consistency due to the uneven distribution of the alumina phase within the copper phase. Our company's alumina copper is produced using a unique method, resulting in material with excellent high-temperature stability, plasticity, and processing performance. Because the added alumina phase has very stable chemical and physical properties, alumina copper offers unparalleled advantages in anti-sticking properties for welding galvanised and nickel-plated plates compared to chromium-zirconium copper and beryllium copper.
