Graphite copper sleeve is a sliding bearing with graphite embedded on a copper alloy substrate as a lubricant, which has self-lubricating properties and does not require additional lubrication. It is made by punching holes in copper sleeves and injecting graphite particles, which form a layer of graphite film on the surface to achieve a self-lubricating effect.

This material combines the advantages of metal alloys and non-metallic wear-resistant materials, possessing both the high load-bearing capacity of metals and the lubricating properties of wear-resistant materials. It is suitable for environments such as no oil, low oil, high temperature, high load, or water. The combination of copper's high conductivity and graphite's thermal conductivity properties gives graphite copper sleeves excellent electrical and thermal conductivity, making them widely used in equipment that requires efficient heat dissipation. Secondly, graphite copper sleeves have good self-lubricating properties. The lubricating characteristics of graphite materials enable these copper sleeves to reduce wear in frictional environments, extend equipment life, and have reliable performance under harsh conditions, significantly reducing the amount of lubricating oil used and equipment maintenance costs. Furthermore, graphite copper sleeves also have excellent performance in high temperature and corrosion resistance under precision machining conditions, making them suitable for demanding industrial manufacturing such as aerospace.

In short, graphite copper sleeves have multiple advantages such as self-lubricating, high temperature resistance, and corrosion resistance, and also have great potential in various industrial applications.
