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
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.
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.
2. Technical parameters of lead bronze
Typical chemical compositions of lead bronze include: copper content of 60-80%, tin content of 5-10%, lead content of 5-25%. This precise composition ratio ensures the stability and consistency of material properties.
In terms of physical properties, the density of lead bronze is 8.5-9.0g/cm³, the melting point is 850-950℃, and the coefficient of thermal expansion is 18.0×10⁻⁶/℃. These parameters determine its stability and reliability in high temperature environments.
Mechanical performance parameters show that the tensile strength of lead bronze is more than 300MPa and the elongation is more than 10%, which ensures the safety and durability of the material during use.
3. Application examples of lead bronze
In the field of mining machinery, lead bronze is widely used in the manufacture of ball mill bearings, crusher bushing and other key components. Its excellent wear resistance and self-lubricating properties ensure long-term stable operation of the equipment.
