In the machinery industry, the use of copper sleeves can be seen everywhere, and different materials have different characteristics, but many people do not know how to choose a copper sleeve that suits them. Shandong Zhengxiang Industrial and Mine will introduce you to the copper sleeve material and its characteristics and working principle. .
ZCuZn38Mn2Pb2: It has good mechanical properties and corrosion resistance, good wear resistance, and good cutting performance.
ZCuSn10Pb5: Corrosion resistant, especially for dilute sulfuric acid, hydrochloric acid and fatty acid. Structural materials, corrosion-resistant and acid-resistant accessories, as well as crusher copper sleeves and bearing bushes.
ZCuPb10Sn10: Good lubrication, wear resistance and corrosion resistance, suitable for bimetal casting materials. Vehicle bearings, internal combustion engine copper bearings with a peak load of 100Mpa, piston pin sleeves, friction plates, etc.
ZCuZn25Al6Fe3Mn3 high-strength aluminum brass, the highest strength among special brass. It has high strength, high hardness, high wear resistance, moderate plasticity and good corrosion resistance. Therefore, it is used to cast high-load wear-resistant weights on heavy machinery.
ZCuAl9Mn2, ZCuAl9Fe4, aluminum bronze has high strength, high density and stable chemical properties. Commonly used in valve bodies, worm gears, nuts, pipe fittings, etc.
ZCuSn10P1 is a typical tin-phosphorus bronze with high hardness and wear resistance. It can be used to make parts that work under heavy loads, high speeds and higher temperatures, and are subject to strong friction, such as connecting rod bushings, gears, worm gears, etc.
ZCuSn6Zn6Pb3, ZCuSn5Zn5Pb5, can be used to manufacture wear-resistant parts such as bushes, gears, and worm gears that work under medium load and speed.
Quality issues have always been a matter of concern to all of us, so how to distinguish the quality of copper sleeves? After reading the following four points, everyone will have a certain understanding of some common copper sleeves.
Check out the materials he uses. Frankly speaking, the quality of copper cast copper is very high. Some low-quality products have lower production costs. As a result, traders often trade at low prices, low prices and high quality, and high-quality copper skateboards are usually within the specified weight range.
High-quality copper sleeves are usually made of aluminum bronze and tin bronze. Tin bronze alloy has high mechanical properties, wear resistance and corrosion resistance, easy cutting, good brazing and welding performance, small shrinkage coefficient and no magnetic.
Aluminum bronze is a high-strength, wear-resistant aluminum bronze containing iron and manganese. Harden after quenching and tempering. It has good high temperature corrosion resistance and oxidation resistance in the atmosphere, fresh water and sea water. It has good etchability, good machinability, weldability and solderability, and good pressure handling in hot conditions.
