Product type
Phosphor bronze is a copper alloy that primarily consists of copper, tin, and phosphorus. It is known for its excellent corrosion resistance, high fatigue strength, and good wear resistance. The addition of phosphorus enhances the alloy's strength and stiffness, making it suitable for various applications in harsh environments.
| Composition | Copper, tin, and phosphorus |
| Typical tensile strength | 400 to 700 MPa |
| Typical hardness | Brinell hardness of 80 to 150 |
| Standard forms | Sheets, rods, wires, and tubes |
| Melting point | Approximately 950 to 1050 °C |
When selecting phosphor bronze, consider the specific application requirements such as tensile strength, hardness, and corrosion resistance. Be sure to specify the desired composition and any relevant standards or certifications. For large projects, it is important to determine the quantity needed to ensure proper supply and pricing.
