The Composition and Manufacturing Process of CuPb10Sn10 Bimetallic Bushings

Material Breakdown and Properties

CuPb10Sn10 bimetallic bushings are crafted with precision, utilizing a carefully balanced alloy composition. The primary component, copper (80%), provides the foundation for the bushing's strength and durability. Lead (10%) contributes to the self-lubricating properties, while tin (10%) enhances the overall hardness and wear resistance of the alloy.

This unique composition results in bushings with impressive characteristics:

  • Operating Temperature Range: -40°C to 150°C
  • Hardness: 60-75 HB
  • Density: 8.7 g/cm³
  • Thermal Conductivity: 50 W/(m·K)

These properties make CuPb10Sn10 bimetallic bushings suitable for a wide range of applications, particularly in environments where high loads, temperature fluctuations, and continuous operation are common.

Manufacturing Techniques

The production of CuPb10Sn10 bimetallic bushings involves sophisticated manufacturing processes to ensure optimal performance and durability. The process typically includes:

  1. Sintering: The copper alloy is sintered onto a high-quality low-carbon steel backing, creating a strong bond between the two materials.
  2. Secondary Sintering: This step further enhances the bonding strength and optimizes the load-bearing capacity of the bushing.
  3. Secondary Extrusion: The final extrusion process refines the bushing's structure, improving its overall performance characteristics.

Advanced manufacturing techniques allow for the creation of various surface features on the copper alloy layer, such as oil grooves, oil holes, and pockets. These features enhance the bushing's performance in applications where continuous lubrication is challenging or impossible.
