Abstract

La matière selon l'invention est sous la forme d'une billette allongée mécaniquement formée d'au moins une première matière en métal bon conducteur d'électricité et d'une seconde matière moins malléable et plus oxydable que la première matière, la seconde matière étant choisie dans le groupe formé par les métaux, les oxydes métalliques, les alliages métalliques et leurs mélanges, la billette comportant des premières et des secondes zones alternées s'étendant sur toute la longueur de la billette et sensiblement symétriques et coaxiales autour de l'axe longitudinal, les premières zones 12 étant pratiquement formées de la première matière et les secondes zones 14 étant formées pratiquement par la seconde matière. Cette matiere convient en particulier pour former des contacts électriques de fermeture et de coupureThe material according to the invention is in the form of an elongated billet mechanically formed of at least a first material of metal which is a good conductor of electricity and of a second material which is less malleable and more oxidizable than the first material, the second material. being chosen from the group formed by metals, metal oxides, metal alloys and their mixtures, the billet comprising first and second alternating zones extending over the entire length of the billet and substantially symmetrical and coaxial around the longitudinal axis, the first areas 12 being substantially formed from the first material and the second areas 14 being substantially formed from the second material. This material is particularly suitable for forming electrical closing and breaking contacts.
