    Product Detail

    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.
    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.

    Frequently Asked Questions

    What is the typical lead content in lead bronze?

    The lead content in lead bronze is typically between 5% and 25%. This content can be customized and adjusted depending on specific application requirements.

    What are the mechanical properties of lead bronze?

    Lead bronze exhibits outstanding wear and fatigue resistance. It has a hardness range of 80-120HB and a tensile strength exceeding 300MPa, making it ideal for heavy load conditions.

    How does lead bronze achieve low friction?

    During friction, the lead particles within the alloy form a lubricating film. This self-lubricating mechanism reduces the friction coefficient to as low as 0.01-0.05, significantly lowering component wear.

    What are the machining and casting advantages of lead bronze?

    Lead bronze has excellent fluidity and low shrinkage, yielding a casting rate of over 95%. In machining, it allows cutting speeds above 150m/min and extends cutting tool life by up to 30%.

    In what industries is lead bronze commonly applied?

    It is widely used in heavy machinery for bearings and bushings, in shipbuilding for seawater corrosion-resistant propeller and rudder bearings, and in energy equipment for turbine and generator bearings.
