During equipment installation and design, we often come into contact with copper sleeves, which are often designed between contacts that are relatively friction or folding. Sometimes, seeing different equipment using copper jackets of different materials in different use environments, let's briefly introduce what kind of copper jacket has good wear resistance? The commonly used copper sleeve material is aluminum, bronze, tin bronze and brass, each material is divided into many varieties.

For example, aluminum bronze has ZCuAL9Fe4, ZCuAL10Fe3, ZCuAI9Fe4Ni4Mn2, etc., tin bronze has ZQSn5-5-5, ZQSn6-6-3, ZQSn10-1, ZQSn10-10, etc., brass has H58, H59-1, H62, etc., or copper castings without branding. Some people say that aluminum bronze has high hardness, high wear resistance, high temperature resistance, and aluminum bronze is good. Some say that tin bronze is more resistant to abrasion. Is it true if there is no lack of oil? Some say it can be used for many years like he did. What is the performance of the material of the copper sleeve? Let's look down at ZCuSn6Zn6Pb3, ZCuSn5Zn5Pb5, which can be used to manufacture wear-resistant parts such as bushings, gears, turbines and other wear-resistant parts that work under medium loads and speedsZCuSn10P1 is a typical tin phosphor bronze, with high hardness and wear resistance, which can be used to manufacture parts that work under heavy loads, high speeds and high temperatures, and are subjected to strong friction, such as connecting rod bushings, gears, turbines, etc. ZCuAL9Mn2, ACuAL9Fe4, aluminum bronze have high strength, high compactness and stable chemical properties. Commonly used in valve body, turbine, nut, pipe fittings, etc. ZCuZn25AL6Fe3Mn3 high-strength aluminum brass, the highest strength among special brass, with high strength, high hardness, high wear resistance, moderate plasticity and good corrosion resistance. Therefore, it is used to cast high loads of wear-resistant weights on heavy machinery.
