(57) Abstract :
The present invention relates to a copper-based sintered slide member comprising 0.5 to 20% by weight of tin, 0.1 to 35% by weight
of manganese, 2 to 25% by weight of a solid lubricant and the balance essentially consisting of copper; and a multilayer copper-based
sintered slide member comprising a copper-based alloy sintered layer and a metal backing plate which are formed into an integral
multilayer structure, wherein the copper-based alloy sintered layer comprises 0.5 to 20% by weight of tin, 0.1 to 35% by weight of
manganese, 2 to 25% by weight of a solid lubricant and the balance essentially consisting of copper. The above slide members are in
the form of a lead-free copper-based sintered slide member. The copper-based sintered slide member can exhibit sliding characteristics
similar to or higher than those of lead-containing copper-based sintered slide members and can be suitably used as an oil-containing
sintered slide member, and can also be suitably used even under conditions in high-temperature ranges and/or under dry frictional
conditions in which it may be difficult to use a lubrication oil, and a multilayer sintered slide member capable of exhibiting excellent
sliding characteristics even under high-load conditions.
