Composition and Properties of CuPb10Sn10 Bimetallic Bushings
CuPb10Sn10 bimetallic bushings are meticulously designed to deliver outstanding performance across a wide range of industrial applications, including heavy machinery, automotive systems, and hydraulic equipment. Their precise composition ensures a strong balance between durability, load-carrying capacity, and friction reduction. The bimetal design allows for excellent adaptability under varying loads and speeds, ensuring reliable operation even in harsh conditions with limited lubrication or high temperature fluctuations.
Material Composition
The CuPb10Sn10 alloy features a carefully optimized blend of elements that enhance its overall performance. Comprising 80% copper, 10% lead, and 10% tin, this alloy achieves an ideal balance of strength, lubricity, and wear resistance. Copper provides mechanical integrity and superior heat dissipation, while lead ensures smooth operation through its self-lubricating behavior. Tin contributes to hardness and fatigue strength, making this alloy highly suitable for high-load and high-speed applications.
Physical Properties
CuPb10Sn10 bimetallic bushings exhibit a combination of physical properties that make them highly dependable in demanding environments. With an operating temperature range of -40°C to 150°C, they maintain consistent performance across wide temperature variations. Their hardness, ranging between 60 and 75 HB, offers excellent wear resistance, while a density of 8.7 g/cm³ ensures high material stability. The thermal conductivity of 50 W/(m·K) promotes efficient heat dissipation, reducing the risk of overheating and extending service life.
Structural Characteristics
The bimetallic structure of CuPb10Sn10 bushings consists of a robust steel backing fused with a sintered copper alloy layer, forming a durable and efficient composite. The steel base provides exceptional strength and rigidity, while the copper alloy layer delivers superior anti-friction and load-bearing properties. To further enhance lubrication, the bearing surface can be customized with oil grooves, dimples, or drilled holes. This structural synergy ensures excellent wear resistance, reduced friction, and improved operational reliability even under extreme conditions.
Manufacturing Process and Quality Control
The production of CuPb10Sn10 bimetallic bushings involves a sophisticated manufacturing process that ensures high quality and consistent performance.
Sintering and Extrusion
The manufacturing process typically involves:
- Preparation of the steel backing
- Application of the copper alloy powder
- Initial sintering to bond the materials
- Secondary sintering and extrusion to optimize bonding strength and load-bearing capacity
This multi-step process results in a robust bimetallic structure with excellent adhesion between the steel backing and the copper alloy layer.
Surface Treatment
After the basic structure is formed, the surface of the copper alloy layer can be further processed to create specific features such as:
- Oil grooves for improved lubrication
- Oil pockets for lubricant retention
- Oil holes for lubricant distribution
These surface treatments are customized based on the intended application and operating conditions of the bushing.
Quality Assurance
To ensure that CuPb10Sn10 bimetal bushings meet industry standards and customer requirements, rigorous quality control measures are implemented:
- Material composition analysis
- Dimensional accuracy checks
- Bond strength testing
- Hardness testing
- Microstructure examination
These quality assurance steps help maintain the high performance and reliability of CuPb10Sn10 bimetallic bushings.
