Abstract
Matériau composite à base de cuivre pour contacts électriques
fortement sollicités, contenant au moins un composant de renforcement
dispersé dans la matrice du cuivre. Ce composant de renforcement
comprend un ou plusieurs oxydes stables vis-à-vis du cuivre, tels que
Al₂O₃ et Y₂O₃, qui forment de préférence une dispersion durcissante
dans la matrice du cuivre. Le composant de renforcement peut également
comprendre des fibres courtes constituées de substances stables
vis-à-vis du cuivre, telles que Al₂O₃ et SiC. La teneur en oxydes est
comprise entre 1 % et 10 % en volume; la proportion desdites fibres
courtes est comprise entre 5 % et 25 % en volume.
