China Lead Bronze Suppliers - High Wear and Fatigue Resistance from Reliable Factory

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 the specific application needs.

In terms of mechanical properties, lead bronze shows excellent wear resistance and fatigue resistance. Its hardness can reach 80-120HB, tensile strength of more than 300MPa, fully meet the requirements of heavy load conditions.

The frictional properties of lead bronze are particularly outstanding. 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.

Lead bronze has good casting properties, good fluidity, low shrinkage, and can be used to manufacture parts with complex shapes. Its casting yield can reach more than 95%, which greatly reduces the production cost.

In machining, lead bronze shows excellent cutting performance. The cutting speed can reach more than 150m/min, the tool life is extended by 30%, and the processing efficiency is significantly improved.

Surface treatment is another advantage of lead bronze. Its surface finish is high, easy to electroplating, spraying and other treatment, to meet the needs of different working conditions.

In the field of heavy machinery, lead bronze is widely used in the manufacture of key components such as bearings and bushings. Its excellent wear resistance and self-lubricating properties ensure long-term stable operation of the equipment.

In the shipbuilding industry, lead bronze is used in the manufacture of propeller bearings, rudder bearings and other important parts. Its characteristics of seawater corrosion resistance fully meet the requirements of Marine environment.

In the field of energy equipment, lead bronze is often used to manufacture key components such as turbine bearings and generator bearings. Its high load-bearing capacity and anti-fatigue performance provide a reliable guarantee for the safe operation of the equipment.
