This material consists of pure copper containing ultrafine particles of aluminum oxide (10 nm ave size) which are uniformly dispersed in copper matrix. Aluminum oxide is produced by a process during which oxygen reacts with aluminum in copper lattice in the solid state.

AL2O3 is very hard and thermally stable. It has no solubility in copper and no AL2O3 growth or diffusion occurs at elevated temperatures. These particles strengthen the copper while minimally reduce its electrical and thermal conductivity.
its applications are as follows:
