Copper Alloy Series

Bronze Bushing

This bronze sleeve is made of tin bronze as the base material. The blank piece is produced through centrifugal casting process. Then, according to the customer's requirements, multiple oil grooves are machined on the inner and outer working surfaces of the sleeve for precise processing. This product has excellent mechanical properties, wear resistance and corrosion resistance, and is highly suitable for industrial applications that require high durability, corrosion resistance and high strength.
High tensile strength: The tensile strength exceeds 260 MPa, ensuring stability and durability under heavy load conditions.
Good yield strength: The yield strength exceeds 120 MPa, suitable for continuous pressure without deformation.
Excellent elongation: Good elongation (≥12%), enhancing impact resistance and fatigue performance.
High hardness: The hardness is 70 HB, effectively resisting external wear.
Resistance to wear and corrosion: The addition of tin and lead significantly improves wear and corrosion resistance.
Optional oil groove design: Customizable inner and outer oil grooves according to different application requirements.
