Product Description

Lead bronze, as an important copper base alloy material, plays an irreplaceable role in the industrial field.

I. Material characteristics of lead bronze

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.

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.

Frequently Asked Questions (FAQ)

1. What is the composition of lead bronze?

Lead bronze is a copper-based alloy created by adding lead to a copper-tin base. The lead content typically ranges between 5% and 25%, depending on the specific requirements of the application.

2. Why does lead bronze have excellent wear resistance?

During friction, the lead particles in the alloy form a lubricating film. This reduces the friction coefficient to as low as 0.01-0.05, significantly minimizing the wear and tear of moving parts.

3. What are the key mechanical properties of lead bronze?

Lead bronze features exceptional fatigue resistance and high load-bearing capacity. It exhibits a hardness level of 80-120HB and a tensile strength exceeding 300MPa, making it ideal for heavy-load operations.

4. How easy is it to machine and cast lead bronze?

It has excellent casting properties, offering high fluidity and low shrinkage, resulting in a casting yield above 95%. For machining, it supports cutting speeds over 150m/min and extends tool life by up to 30%, which significantly reduces manufacturing costs.

5. What industries and components utilize lead bronze?

Lead bronze is widely used in heavy machinery (bearings and bushings), shipbuilding (propeller and rudder bearings due to seawater corrosion resistance), and energy equipment (turbine and generator bearings).
