    摘要： Internal oxidized Ag-SnO system alloy electrical contact materials having a moderate initial contact resistance and having no depletion layer is disclosed. The alloy is internal oxidized by having it sandwiched between pure silver thin layers, and is cut horizontally right in two, simultaneously removing the depletion layer from the internally oxidized alloy.

    摘要： An electrical contact material obtained through internally oxidizing a silver alloy which is the solid solution with 3 to 11 weight percent of tin and other solute metal element(s). The alloy material is improved of its contact resistance by diffusing into the silver matrix 0.1 to 5 weight percent of metals having a decomposition and sublimation temperature lower than the melting point of silver and then by internally oxidizing the material.
