Dhruv Metals, Hyderabad, supplies top–grade Aluminium Bronze Bars and Rods for their strength, corrosion resistance, and anti-friction values. Produced from copper-aluminium alloys (generally with 8–12% Al), these bars are ASTM B150 and BS 2874 compliant. Recommended for their wear resistance in corrosive conditions, they find applications in marine, hydraulic, and aerospace applications. The material is highly resistant to oxidation, stress corrosion, and cavitation. The company provides these bars in multiple shapes and sizes that are well-suited for machining, welding, and forging for the power, defense, and heavy engineering sectors.
Aluminium Bronze generally consists of 80–89% Cu, 9–12% Al, and small additions of Fe, Ni, or Mn for better properties. It has tensile strength of 500–750 MPa, yield strength of 200–500 MPa, and elongation of 10–25%. Hardness is 130–220 HB in any condition. The alloy will maintain mechanical strength at high temperatures and possess superior wear, fatigue, and corrosion resistance. It excels in high-load and high-pressure applications, particularly where lubrication is not available. Aluminium Bronze provides excellent weldability and can be stress-relieved to minimize distortion in precision equipment.

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 Rods and Bars find extensive use in ship propellers, valve stems, bearings, worm gears, and hydraulic piston parts. Its wear resistance proves suitable for sliding surfaces, guide bushes, and bushings in heavy-duty machinery. On marine and offshore platforms, they withstand seawater corrosion and cavitation. Aerospace companies use them for structural couplings and landing gear bearings. In chemical industries, they find application in pump shafts, condenser bolts, and agitators. Their anti-sparking feature makes them ideal to be used in hazardous areas of oil, gas, and mining industries. They offer long service life in abrasive and corrosive conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
