本发明系滑动接点材料，其具有6.0质量%以上9.0质量%以下之Cu、0.1质量%以上2.0质量%以下之Ni、0.1质量%以上0.8质量%以下之添加元素M、其余为Ag之组成。该添加元素M系选自Sm、La、Zr所成之群中之至少一种元素。本发明之滑动接点材料具有于Ag合金基质中分散有分散粒子之材料组织，该分散粒子包含至少含有Ni及添加元素M之两者之金属间化合物。该分散粒子中之Ni含量(质量%)与添加元素M之含量(质量%)之比率(KNi/KM)被要求在特定范围内。本发明系耐磨耗性比以往更优异之Ag合金系之滑动接点材料，且系亦可对应于微型马达之高旋转数化之材料。

To provide a Ag alloy-based sliding contact material, which can be applied to micro motors or the like having an increasingly high rotation speed. More particularly, the contact material includes compositions: Cu of no lower than 6.0 mass% and no higher than 9.0 mass%; Ni of no lower than 0.1 mass% and no higher than 2.0 mass%; an additive element M of no lower than 0.1 mass% and no higher than 0.8 mass%; and the balance being Ag. The additive element M is at least an element to be selected from a group of Sm, La and Zr. The sliding contact material has a material structure, in which dispersed are dispersed particles including an intermetallic compound containing at least both Ni and the additive element M in a Ag alloy matrix. It is required that a ratio of a Ni content by mass% and an additive element M content by mass% be within a predetermined range.
