Specializing in the production of copper sleeves for marine equipment, supporting customization and factory direct sales

Zhejiang Mingxu Machinery Manufacturing Co., Ltd. specializes in the production of large copper sleeves and copper sleeves for marine equipment accessories, and can carry out customized production in various forms and standards according to customer needs. It has a complete and scientific quality management system; it has a complete quality inspection system such as component testing and mechanical performance testing, and can provide you with high-quality products.

Copper sleeves are widely used in land mechanical equipment. Almost every kind of mechanical equipment bearing contains copper sleeves, and copper sleeves can be used as self-lubricating bearings. It is also widely used in marine equipment. There are large copper sleeves and small copper sleeves for ships, because ships are mostly operated in oceans, lakes, and rivers, and frequently contact water sources, including fresh water and sea salt water. Especially in seawater, it contains a variety of corrosive substances; and the water pressure is high; therefore, the copper sleeves required for ships need to have pressure resistance and corrosion resistance, which requires strict selection of materials when selecting materials for manufacturing marine shaft sleeves.   Most of the copper sleeves used in general ships are large copper sleeves for heavy equipment. Their manufacturing process is very rigorous, and the chemical composition of the materials used in manufacturing is strictly required, and the manufacturing process is complex. Such a large copper sleeve has both the mechanical properties of steel and the wear resistance of copper. In addition, other rare metal materials are added on the basis of copper, so that the copper sleeve has the corresponding hardness and corrosion resistance. To extend the service life of large marine copper sleeves. The copper sleeves for marine equipment are operated under high load and high speed conditions, so they must have the characteristics of high hardness and strong wear resistance. Therefore, it is necessary to strictly control the selection of materials when manufacturing marine copper sleeves. To ensure the normal operation of marine equipment.

Material of marine equipment copper sleeve

The material of the stern shaft copper sleeve produced by our company is tin bronze. The tin content of tin bronze is generally between 3% and 14%, and it is mainly used to make elastic elements and wear-resistant parts. The tin content of the deformed tin bronze copper sleeve does not exceed 8%, and sometimes phosphorus, lead, zinc and other elements are added. It has high strength, corrosion resistance and excellent casting properties.
Tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage rate. It can be used to produce castings with complex shapes, clear contours and low airtightness requirements. Tin bronze is very corrosion-resistant in the atmosphere, seawater, fresh water and steam, and is widely used in steam boilers and ship parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as wear-resistant parts and elastic parts of high-precision machine tools.
