Product Description
Silicon bronze is a type of bronze where silicon serves as the primary alloying element. In industrial applications, silicon bronze typically contains not only silicon but also small amounts of additional elements such as manganese, nickel, zinc, or others. Silicon has limited solid solubility in copper, which decreases as temperature drops. However, the aging hardening effect of silicon bronze is relatively weak, and it generally does not undergo strengthening heat treatment. This makes it a versatile material for applications where moderate strength and excellent corrosion resistance are required.
Properties of Silicon Bronze Plate
- Corrosion Resistance: Excellent resistance to corrosion, especially in marine and acidic environments.
- High Strength: Offers superior mechanical strength compared to many other copper alloys.
- Weldability: Can be easily welded using common techniques, making it ideal for fabrication.
- Machinability: Can be machined to precise tolerances with appropriate tools.
- Aesthetic Appeal: Has a distinctive golden-brown color, making it suitable for decorative applications.
- Non-Sparking: Safe for use in explosive or flammable environments.
Common Silicon Bronze Alloys
- C65500 (High-Silicon Bronze A): Contains 96% copper, 3% silicon, and 1% manganese. Known for high strength and corrosion resistance.
- C65100 (Low-Silicon Bronze B): Contains 98.5% copper, 1.5% silicon, and trace amounts of other elements. Offers good weldability and formability.
Common Silicon Bronze Plate Specifications
Thickness: Available in various thicknesses, typically ranging from 0.1 mm to 50 mm.
