"High-speed cutting phosphor bronze" is an alloy made by adding tin, lead, and a small amount of phosphorus to copper. The cutting processability, properties, and applications vary depending on the amounts of tin and lead used. "C5341" is an alloy that contains 3.5% to 5.8% tin and 0.8% to 1.5% lead added to copper, while "C5441" is an alloy that contains 3% to 4.5% tin, 3.5% to 4.5% lead (with stock items being less than 4%), and 1.5% to 4.5% zinc added to copper. It has good cutting processability and possesses the mechanical properties of phosphor bronze, making it widely used in various processing methods for products. 【Features】 ■ Mechanical strength ■ High elasticity ■ Cutability ■ Fatigue resistance ■ Wear resistance *For more details, please download the PDF or feel free to contact us.
