Electrolytic copper is used as raw material with various trace metal elements. QBe1.9 beryllium copper plate. Sintered at high temperature and processed by air pressure centrifugal casting, it has high hardness, excellent wear resistance, is not easy to cause seizure, has good casting performance and cutting performance, and has good corrosion resistance in the atmosphere and fresh water. In the absence of lubricants and water-based lubricants, it has good sliding and self-lubricating properties and is easy to cut.
Poor casting performance, good corrosion resistance to dilution, simple castings used in general-purpose structural parts, ships, instruments, etc., such as sleeves, bushings, bearing bushes, sliders, etc., self-lubricating bearings, special materials Lubricating bearings, according to different uses and working conditions, choose different self-lubricating bearings, one of which is a large category of solid inlaid self-lubricating bearings (JDB for short) is a new type of lubricating bearing that combines the characteristics of metal bearings and oil-free lubricating bearings.
The substrate bears the load, and the special solid lubricating material plays a lubricating role. It has high bearing capacity, impact resistance and high temperature resistance.
