Copper sleeves, also known as copper shaft sleeves, are divided into many types, including copper rollers for machines, copper bearings, etc. They are used in various light, large and heavy machinery and are important components of machinery. The product has the function of traditional tin bronze bearings.
It is made of electrolytic copper as raw material and matched with a variety of trace metal elements, sintered at high temperature, and processed by air pressure centrifugal casting. It has high hardness, excellent wear resistance, and is not easy to produce seizure. It has good casting performance and cutting performance, and has good corrosion resistance in the atmosphere and fresh water. In the absence of lubricants and using water-based lubricants, it has good sliding and self-lubricating properties, is easy to cut, has poor casting performance, and has good corrosion resistance to dilute sulfuric acid. General-purpose structural parts, simple-shaped castings used in ships, instruments, etc., such as sleeves, bushings, bearings, sliders, etc.
