Copper alloy use of a copper alloy bearing having a copper alloy and method for producing a bearing composed of a copper alloy

摘要

The present invention relates to a copper alloy, for example CuNi6Sn5Fe2P0.15, which has hard particles, for example Fe3P or Fe2P, and optionally a solid lubricant, for example hexagonal boron nitride or graphite. The present invention further relates to the use of the copper alloy as a bearing and to a bearing having the copper alloy. Furthermore, the present invention also relates to a method for producing a bearing having a copper alloy, wherein the metal powder is produced, for example by melt atomization, optionally adding hard particles and optionally a solid lubricant to the powder, the powder is sintered onto the substrate. Finally, the present invention relates to an alternative method of manufacturing a bearing, in which a copper alloy is applied to a substrate by casting or plating or the bearing is entirely made of copper alloy.
