    摘要： An object of the present invention is to provide a material for a sliding contact whose alloy composition does not contain an environmentally detrimental substance such as Cd, which exhibits excellent contact resistance, whose electrical functions are good and free of time-course variation, and which further exhibits excellent wear resistance. The material for a sliding contact assumes the form of an Ag—Zn—Pd, Ag—Zn—Pd—Cu, Ag—Zn—Pd—Ni, or Ag—Zn—Pd—Cu—Ni alloy. In the compositions of these alloys, the Zn content is 0.1-3.0% by weight, the Pd content is 0.1-1.5% by weight, and the balance is Ag. When Cu is contained, the Cu content is 0.1-3.0% by weight. When Ni is contained, the Ni content is 0.01-0.5% by weight. Zn, Pd, and Cu are present in the Ag &agr; phase in the form of solid solution. Ni particles are finely dispersed in the alloys. A composite clad material is formed through use of the material for a sliding contact. A commutator manufactured through use of the composite clad material is incorporated into a small-sized direct current motor used in a household electrical appliance.

    摘要： An Ag--Cu alloy for a sliding contact containing:a) 0.1 to 8.0 wt. % of Cu, based on the weight of the alloy, wherein at least 70 wt. % of the Cu contained in the alloy is solid-solubilized in an Ag-.alpha.-phase; andb) 0.1 to 4.0 wt. %, based on the weight of the alloy, of at least one metal selected from the group consisting of Ge, Ni, Sn, In, Zn, Mg, Mn, Sb, Pb and Bi.The Ag--Cu alloy is desirably utilized to form a composite with a Cu or Cu alloy base material. Such composite has been found to be very useful for fabricating the commutator of a compact DC motor.

    摘要： A method for manufacturing an electric contact material is provided which can prevent it from being adhesively melted even when being exposed to high temperatures resulting from an arc induced by an electric current being turned on or off. Also an electric contact material which is manufactured by the method and a thermal fuse are provided.A surface layer portion of an alloy containing 1 to 15 mass % of Cu, 0.01 to 0.7 mass % of Ni, and the remainder of Ag and unavoidable impurities is supplied with an amount of oxygen exceeding the amount of oxygen required for internal oxidation of Cu to form an oxygen concentrated layer. This alloy can serve as an electric contact material.This electric contact material is formed into a movable electrode, which is in turn employed for a thermal fuse.
