copper of rolling mill and copper nut

copper of rolling mill and copper nut：

Copper sleeves are divided into many types, including machine copper rollers, copper bearings, etc. Oil lubricated bearings are used in various large and heavy machinery and are important components of machinery.

Copper sleeves, also called copper bushings, are divided into many types, including machine copper rollers, copper bearings, etc. It is used in various light industry, large and heavy machinery and is an important component of machinery. The product has traditional tin bronze bearing functions. It is made of electrolytic copper as raw material and mixed with a variety of trace metal elements. It is sintered at high temperature and processed by air pressure centrifugal casting. It has high hardness, excellent wear resistance, is not prone to 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, easy cutting, poor casting properties, and good corrosion resistance to dilute sulfuric acid. General-purpose structural parts, simple-looking castings used in ships, instruments, etc., such as sleeves, bushings, bearings, sliders, etc.

The definition of a copper nut is a nut made of copper material (usually lead brass, such as H59, H62). The copper nuts we come into contact with daily are mainly hexagonal nuts or other copper nuts that match bolts.
