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:
C65100(low silicon bronze)：Silicon content 0.8 - 2.0%，It has excellent cold workability and can be easily cold rolled, deep drawn, bent and stretched. It is an ideal choice for manufacturing thin plates and complex shaped parts.
C65500(High silicon bronze): Silicon content 2.8 - 3.8%，Due to its higher silicon and manganese content, it is superior to C65100 in strength, hardness and wear resistance.
QSi3-1: China's silicon bronze grades. Silicon (Si) and manganese (Mn) are the main alloying elements. High silicon provides strength and hardness, while manganese provides deoxidation and solid solution strengthening. It does not contain nickel.
QSi1-3: China's silicon bronze grades. Silicon (Si) and nickel (Ni) are the primary alloying elements. Low silicon content combined with high nickel content creates a unique performance combination. Nickel significantly enhances the alloy's heat resistance, corrosion resistance, and creep (stress relaxation) resistance.
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.
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.
Architectural: Chosen for its appealing finish and durability in construction materials.
Excellent Corrosion Resistance: Silicon bronze resists corrosion in harsh marine and chemical environments.
High Strength and Durability: These alloys are designed for applications requiring high tensile strength.
Ease of Machining: Many grades of silicon bronze offer excellent machinability, especially in manufacturing components.
Versatility in Use: Available in wire, rod, and plate forms, suitable for a range of industries and applications.
Q: What is the difference between C65100 and C65500 ?
A: C65100 has excellent cold workability, allowing for easy cold rolling, deep drawing, bending, and stretching. It is ideal for manufacturing thin sheets and complex-shaped parts.
C65500 has poor cold workability. Its high silicon content causes it to harden and become brittle more quickly in the cold state (extremely high work hardening rate), making complex cold forming difficult. It is more commonly used in hot-worked or machined forms.
C65500 has better machinability than C65100. The higher silicon content allows for easier chip breakage, resulting in a smoother surface finish and making it more suitable for machining on automatic lathes.
However, both have good hot workability, are suitable for hot rolling, hot forging and other processes, and have excellent corrosion resistance, including resistance to seawater, atmosphere and many chemical media.
Q: Can silicon bronze be used for welding?
A: Yes, silicon bronze alloys, especially in wire form, are often used for welding due to their smooth surface finish and strong bonding properties.
