Al2O3 1.1 - High-performance sintering material

Aluminium dispersion-strengthened copper

WIRBALIT® CA11 consists of pure copper with ultra-fine aluminium oxide particles (10nm), which are homogeneously distributed in a copper matrix.

The resulting Al₂O₃ shows high hardness and high thermal stability.

Due to its high temperature resistance, Wirbalit® CA11 represents an alternative for the substitution of Beryllium material in many applications.
