Lead bronze, as an important copper base alloy material, plays an irreplaceable role in the industrial field. It offers a unique combination of strength and lubricity for demanding applications.
Lead bronze is a special alloy made by adding lead element on the basis of copper-tin alloy. The addition of lead significantly improves the frictional properties of the material, and the lead content is usually between 5%-25%, which can be adjusted according to specific application needs.
In terms of mechanical properties, lead bronze shows excellent wear resistance and fatigue resistance. Its hardness can reach 80-120HB, with tensile strength of more than 300MPa, fully meeting the requirements of heavy load conditions.
The frictional properties are particularly outstanding. Lead particles form a lubricating film during friction, with a friction coefficient as low as 0.01-0.05, significantly reducing the wear of moving parts.
Lead bronze has good casting properties, high fluidity, and low shrinkage, making it ideal for manufacturing parts with complex shapes. Its casting yield can reach more than 95%, which greatly reduces production costs.
In machining, it shows excellent cutting performance. The cutting speed can reach more than 150m/min, extending tool life by 30% and significantly improving processing efficiency.
Surface treatment is another advantage. Its surface finish is high, making it easy to electroplate, spray, or apply other treatments to meet the needs of different working conditions.
In heavy machinery, lead bronze is widely used for key components such as bearings and bushings. Its excellent wear resistance and self-lubricating properties ensure long-term stable operation.
In the shipbuilding industry, it is used for propeller bearings and rudder bearings. Its seawater corrosion resistance fully meets the requirements of marine environments.
In energy equipment, it is often used for turbine bearings and generator bearings. Its high load-bearing capacity and anti-fatigue performance provide a reliable guarantee for safe operation.
Lead bronze has become an indispensable material in modern industry due to its excellent properties and wide range of applications. Choosing high-quality lead bronze products will provide reliable performance assurance for your equipment.
The addition of lead creates lead particles that act as a solid lubricant, significantly reducing the friction coefficient and improving wear resistance.
Lead bronze typically exhibits a hardness range of 80-120HB, making it suitable for heavy-duty industrial applications.
Yes, it has excellent seawater corrosion resistance, which is why it is frequently used for propeller and rudder bearings in shipbuilding.
