Round
INTRODUCTION
Phosphor Bronze Round Bar is a high-performance copper alloy primarily composed of copper, tin, and a small amount of phosphorus. The addition of tin improves strength and corrosion resistance, while phosphorus enhances wear resistance and stiffness. Due to these characteristics, phosphor bronze round bars are widely used in industries requiring durable and precision-engineered components.
