Rich in extensibility, good for bending processing, and excellent plating properties! Phosphor bronze round bars are available in various sizes from domestic materials.
"Aluminum bronze" is an alloy made by adding tin and a small amount of phosphorus to copper. "C5191" is an alloy with 5.5% to 7% tin added to copper, while "C5212" is a material that has increased hardness by adding even more tin. Since C5191 and C5212 do not contain lead, they are difficult-to-machine materials in precision cutting processes, but they are highly ductile and have good bending and plating properties. 【Features】 ■ Mechanical strength ■ High elasticity ■ Corrosion resistance ■ Fatigue resistance ■ Wear resistance *For more details, please download the PDF or feel free to contact us.

Company information
Our company has been a primary wholesaler specializing in unique non-ferrous metals, such as [phosphor bronze bars, nickel silver bars, and beryllium copper bars], since our founding in 1964. Since our establishment, we have always worked with a spirit of gratitude and challenge under the management philosophy of "coexistence and mutual prosperity." By maintaining a sense of gratitude, our actions and responses change. As a result, we believe we can grow into a company that earns the trust of everyone and society.
