Aluminium Bronze Alloys Sheets, Rods, Bars & Castings

Product Overview

Aluminium Bronze Alloys are high-performance copper-based alloys known for their exceptional strength, corrosion resistance, and durability in aggressive service environments. R V Metal Corporation supplies Aluminium Bronze in multiple product forms including sheets, rods, bars, and castings, engineered to perform reliably in marine, offshore, heavy engineering, power generation, oil & gas, and chemical processing applications. The presence of aluminium enhances resistance to seawater corrosion, oxidation, cavitation, and wear, while also delivering excellent mechanical strength compared to conventional brasses and bronzes.

Our Aluminium Bronze products are available in standard and custom grades, offering a balanced combination of high tensile strength, good fatigue resistance, and excellent machinability for both wrought and cast forms. These alloys maintain structural integrity under high loads, elevated temperatures, and corrosive conditions, making them a preferred material for critical components such as pump parts, valves, bushings, bearings, propeller shafts, fasteners, and structural elements. With strict quality control and compliance to international standards, R V Metal Corporation ensures consistent metallurgy, dimensional accuracy, and long service life across all Aluminium Bronze alloy products.
