        What material is copper sleeve wear-resistant?
        2023-08-29

        During equipment installation and design, we often come into contact with copper sleeves, which are usually designed between contacts with relative friction or folding. Sometimes, see different equipment in different use of different materials of copper jackets, let's briefly introduce what kind of copper jacket wear resistance is good

        The commonly used copper jacket materials are aluminum bronze, tin bronze and brass, and each material is divided into many varieties. For example, aluminum bronze has ZCuAL9Fe4, ZCuAL10Fe3, ZCuAl9Fe4Ni4Mn2, etc., tin bronze has ZQSn5-5-5, ZQSn6-6-3, ZQSn10-1, ZQSn10-10, etc., brass has H58, H59-1, H62, etc., or no brand of copper casting. 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 has better wear resistance. Is that true if there is no shortage of oil? Some say he can use it for years. What is the performance of the material of the copper sleeve? Let's look down

        ZCuSn6Zn6Pb3, ZCuSn5Zn5Pb5, can be used to manufacture bushings, gears, turbines and other wear parts under moderate load and speed

        ZCuSn10P1 is a typical tin-phosphorus bronze with high hardness and wear resistance, which can be used to manufacture parts with heavy loads, high speeds and high temperatures and subjected to strong friction, such as connecting rod bushings, gears, turbines, etc

        ZCuAL9Mn2, ACuAL9Fe4, aluminum bronze has high strength, high density, and stable chemical properties. Commonly used in valve body, turbine, nut, pipe fittings, etc

        ZCuZn25AL6Fe3Mn3 High strength aluminum brass, the highest strength in special brass, with high strength, high hardness, high wear resistance, moderate plasticity and good corrosion resistance. Therefore, it is used for casting high load wear-resistant weight on heavy machinery

        Jiaxing Rongchang Bearing is a professional production of plain bearings company, is approved by the relevant state departments registered enterprises. Main products: copper sleeve, copper bearing, copper slide, copper slider, copper worm gear, sliding bearing seat and other copper products. Our company adopts the advanced production process ---- centrifugal casting, the copper sleeve and copper bearing shell produced can significantly improve the tightness and wear resistance of the castings compared with sand casting, and have good tensile strength, flexural strength and tensile ratio. The material of copper sleeve is brass, tin bronze, aluminum bronze, etc. The company adheres to the principle of "integrity first, customer first", and has established long-term friendly cooperative relations with many enterprises.
