High Performance Tellurium Copper Alloy Material from China Suppliers and Factory for Industrial Applications
As a high performance copper based alloy, lead bronze performs well under heavy load and low speed.
First, the material advantages of lead bronze
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.
High Load-Bearing Capacity
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.
Excellent Corrosion Resistance
Lead bronze also has excellent corrosion resistance. It has good corrosion resistance in seawater, fresh water and other media to ensure the service life of the material.
