This copper-based alloy is celebrated for its remarkable strength, resistance to corrosion, and durability, particularly in marine and heavy engineering settings. At Rupal Metals, we employ cutting-edge manufacturing techniques and rigorous quality control to uphold the highest standards for our products. Catering to sectors like aerospace, marine, oil & gas, and general engineering, we provide precision-engineered solutions that come with dependable supply and competitive pricing. Our Aluminium Bronze bars and rods are recognized across the nation for their durability, performance, and extended service life.
Aluminium Bronze is a copper alloy that typically contains 8–12% aluminium, along with trace amounts of iron, nickel, and manganese to enhance its strength and resistance to corrosion. These bars and rods boast impressive tensile strength (up to 850 MPa), exceptional wear resistance, and outstanding performance in seawater and harsh environments. They also demonstrate good fatigue resistance and are non-sparking. The alloy maintains excellent dimensional stability, making it suitable for welding and machining. Its unique blend of mechanical properties makes Aluminium Bronze perfect for high-load, high-wear, and corrosion-sensitive industrial applications.

To select the right aluminum bronze bar, consider factors like strength, corrosion resistance, wear resistance, temperature conditions, and alloy composition. Ensure compatibility with your specific application environment and mechanical requirements.
Aluminium bronze rods are available in various sizes, typically ranging from 1/8" to 6" in diameter. Finishes include as-forged, rough-turned, polished, and anodized for enhanced corrosion resistance.
Yes, aluminum bronze bars can be welded, typically using TIG or MIG welding methods. Preheating may be required to prevent cracking, and post-weld heat treatment helps ensure strength and integrity.
Aluminium Bronze Bars and Rods find extensive use in industries that demand high strength, excellent corrosion resistance, and superior wear performance. They are frequently employed in marine hardware, ship propellers, shafts, and underwater fasteners due to their exceptional resistance to saltwater corrosion. In the oil & gas and petrochemical industries, they are essential components in valve construction and other critical applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
