Silicon bronze alloys are high-performance materials primarily composed of copper and silicon, with minor additions of elements like manganese, zinc, and nickel. This versatile alloy offers exceptional corrosion resistance, strength, and excellent casting properties, making it ideal for a wide range of industrial applications. Silicon bronze products are often used in demanding sectors like aerospace, marine, and chemical industries.
We offer a diverse selection of silicon bronze products, available in various forms such as wire, rod, and plate. Each product is designed to meet specific performance needs, and our range includes:
Silicon Bronze Wire: Ideal for welding and other applications where flexibility and corrosion resistance are critical.
Silicon Bronze Rod: Perfect for machining into components, providing strength and durability.
Silicon Bronze Plate: Suitable for manufacturing heavy-duty parts with outstanding resistance to wear and corrosion.
Silicon bronze alloys are available in various grades, each with specific features and elemental compositions:
QSi3-1: This grade is characterized by low lead content (0.03%) and provides good corrosion resistance. It is ideal for use in marine applications and industrial environments.
QSi1-3: Contains 0.15% copper and has superior corrosion resistance properties, making it suitable for architectural applications.
QSi3.5-3-1.5: Known for its strength, this alloy contains 1.2-1.8% iron and is perfect for applications requiring both high strength and corrosion resistance.
C65100 and C65500: These grades contain higher iron content (0.8-1.5%), which enhances their strength and machineability.
C83600: With a higher zinc content (4.0-6.0%), this alloy is designed for applications in harsh environments, offering high strength and excellent corrosion resistance.
CuNi2Si: An alloy with excellent properties for marine and chemical industries, offering resistance to corrosion and stress.
Silicon bronze alloys offer a balance of mechanical strength and excellent physical properties, including:
Density: Ranges from 8.53 g/cm³, making it suitable for both welding and casting applications.
Tensile Strength: Silicon bronze alloys generally exhibit tensile strengths ranging from 105 MPa to 415 MPa, depending on the grade.
Hardness: Silicon bronze typically features a hardness rating that ensures superior resistance to scratching and wear compared to pure copper.
Corrosion Resistance: Known for excellent resistance to corrosion, even when submerged in chemicals and seawater.
Silicon bronze alloys are employed across several industries, including:
Aerospace: Used in bearing cages, raceways, and spacers due to their self-lubricating properties.
Marine: Preferred for shafting, hardware, and fittings in underwater applications.
Chemical Industry: Utilized in environments requiring resistance to chemicals and high temperatures.
