Abstract

Elément de contact en une matière pour contacts électriques non sujette au phénomène de migration fine qui contient en tant que matériau composite, pour une partie en poids prépondérante, au moins deux constituants métalliques solubles l'un dans l'autre et dont au moins l'un est en métal précieux. Les constituants solubles l'un dans l'autre sont disposés dans le matériau composite de façon hétérogène en tant que constituants métalliques purs. L'invention est applicable d'une manière générale au domaine des contacts électriques et en particulier à la fabrication de rivets de contact plaqués.
