At Victor Sheets and Plates, we focus on quality craftsmanship and consistency, ensuring every piece meets international standards. Our Phosphor Bronze Circles are valued by industries that demand durability, reliability, and excellent machinability for components that must perform under constant motion or pressure.
Phosphor Bronze Circles are primarily composed of copper (around 88–95%), with tin (4–10%) and a small percentage of phosphorus (up to 0.35%). This composition enhances the alloy’s hardness, strength, and resistance to fatigue and corrosion. The addition of phosphorus improves wear resistance and stiffness while maintaining good ductility and formability. Phosphor bronze also offers excellent spring properties and low friction, making it suitable for precision components. Its balance of toughness and workability ensures consistent mechanical performance, even in demanding or repetitive-use conditions.
