Cast copper bushings are widely used bearing components in various machinery and equipment, typically made from different copper alloy materials to meet diverse performance requirements and application conditions. Centrifugal casting and continuous casting are two common methods used to produce copper bushings with specific shapes and sizes.

Standard Materials:

  • CuSn12: This copper alloy contains 12% tin and offers good corrosion resistance and mechanical properties, commonly used for bearings in marine and chemical environments.
  • CuSn7ZnPb (RG7): This alloy, containing tin, zinc, and lead, provides excellent wear resistance and load-bearing capacity, suitable for high-load bearing applications.
  • CuSn10: A copper alloy with 10% tin, it offers higher strength and good corrosion resistance, suitable for medium-load bearings.
  • CuSn12: Similar to CuSn10 but with a higher tin content, offering better performance.
  • CuPb10Sn: This alloy contains lead and tin, providing good lubricity and wear resistance, suitable for bearings requiring low friction and high load-bearing capacity.
  • CuAl10Ni: Combining the benefits of aluminum and nickel, this alloy offers high strength and good corrosion resistance, suitable for high-performance applications.
  • CuSn10Zn (RG10): Containing tin, zinc, and copper, this alloy has good overall performance and is suitable for various conditions.
  • CuZn25Al5: This alloy has a higher proportion of zinc and aluminum, offering good strength and corrosion resistance, suitable for demanding applications.
  • CuSn5ZnPb (RG5): Containing tin, zinc, and lead, this alloy provides good wear resistance and load-bearing capacity, suitable for general bearing applications.

Custom Designs: Besides standard materials, copper bushings can be specially designed and manufactured according to customer-specific requirements. These custom designs may include:

  • Integrated Cast Flanges: Copper bushings can be designed with integrated cast flanges for easy installation and fixation.
  • Water Inlet Holes: To meet cooling or lubrication needs, copper bushings can be designed with water inlet holes.
  • Lipped Edges: Copper bushings can feature lipped edges to provide additional sealing or support.
  • Inner and Outer Steps: To accommodate different assembly requirements, copper bushings can have inner and outer steps.
  • Milled Grooves: Copper bushings can be machined with milled grooves to offer additional positioning or fixation capabilities.
