Abstract
PURPOSE:To make it possible to obtain a stable material receiving low contact resistance with low contact pressure by making the thick ness of a metal layer formed by the diffusion of tin atoms in the coating layer and copper atoms in the basic material or in the foundation in the molten condition by heating at 0.4 to 1.2mum. CONSTITUTION:In the molten condition by heating, the thickness of a metal layer formed by the diffusion of the tin atoms in the coating layer and the copper atoms in the basic material or the foundation is made 0.4 to 1.2mum. That is, by heating and melting the tin or tin-lead alloy layer on a copper or copper alloy, a copper-tin alloy layer including the Cu6Sn5 phase and the Cu3Sn phase as a diffusion product of the copper in the basic material or in the foundation and the tin in the coating layer, and also including the other basic material elements, is formed. By maintaining such a molten condition for several seconds to more than 10 seconds, the thickness of the alloy layer is made 0.4 to 1.2mum. The Vickers hardness of the alloy layer in made up to 350 to 450, which is remarkably hard compared with the hardness less than 50 of the residual tin or tin-lead alloy layer on the upper layer. Consequently, since the sliding and the gearing are made smooth when a contact pressure is inflicted to the material as an electric contact to contact it, a stable material with a low contact resistance can be obtained.
