As a high performance copper based alloy, lead bronze performs well under heavy load and low speed.
Lead bronze has excellent self-lubricating properties. Lead particles form a lubricating film during friction, and the friction coefficient can be as low as 0.01-0.05, which significantly reduces the wear of moving parts.
In terms of load-bearing capacity, lead bronze performs well. The allowable specific pressure can reach more than 25MPa, which fully meets the requirements of use under heavy load conditions.
It also possesses excellent corrosion resistance in seawater, fresh water and other media to ensure the extended service life of the material.
Chemical Composition: Typical ratios include copper (60-80%), tin (5-10%), and lead (5-25%). This precise composition ensures stability and consistency.
Physical Properties: The density is 8.5-9.0g/cm³, with a melting point of 850-950℃. The coefficient of thermal expansion is 18.0×10⁻⁶/℃, ensuring reliability in high-temperature environments.
Mechanical Performance: Tensile strength exceeds 300MPa and elongation is more than 10%, ensuring safety and durability during use.
Mining Machinery: Widely used for ball mill bearings and crusher bushings. Its wear resistance and self-lubricating properties ensure long-term stable operation.
Metallurgical Equipment: Used in rolling mill bearings and continuous casting machine bearings, providing high load-bearing capacity and anti-fatigue performance.
Construction Machinery: Frequently used for excavator bearings and bulldozer bushings due to its superior impact resistance.
Lead bronze, with its excellent performance and wide range of applications, has become the ideal choice for heavy duty conditions. Choosing lead bronze products will provide you with reliable performance assurance for your equipment.
Lead bronze offers exceptional self-lubricating properties, high load-bearing capacity (over 25MPa), and excellent corrosion resistance in both seawater and fresh water environments.
Due to the lubricating film formed by lead particles, the friction coefficient of lead bronze can be as low as 0.01 to 0.05.
