Abstract

1. A process for the production of an electrical contact formed by a substrate of carbon fibres of small diameter which are aligned in a preferential direction and impregnated with a metal or metal alloy which is a good conductor of electric current, characterized in that the carbon fibres forming the substrate are between 2 and 50 mu m in diameter and that after impregnation under pressure with a metal or alloy which does not react with the carbon, the material produced in that way is subjected to a hot extrusion operation.
