AB2 (Aluminium Bronze) | BS1400 AB2 Alloy Castings

At Conex Metals, we are an established manufacturer and exporter of AB2 Aluminium Bronze Alloy Castings, produced in strict accordance with British Standard BS1400: AB2. Known for its exceptional strength, superior corrosion resistance, and outstanding wear properties, AB2 aluminium bronze is one of the most versatile and high-performing bronze alloys used today. It is widely recognised for its performance in marine environments, resisting seawater corrosion, cavitation, and stress fatigue. We at Conex Metals produce precision AB2 bronze castings for critical engineering applications, serving customers in industries such as marine, offshore, pumps & valves, power generation, mining, and heavy engineering. Overview of AB2 Aluminium Bronze AB2 is a high-strength aluminium bronze alloy with added nickel and iron, further enhancing its corrosion resistance and mechanical properties. This makes it well-suited for use in marine and seawater-exposed parts, where reliability under harsh service conditions is essential. Its strength, wear resistance, and high fatigue resistance make it ideal for dynamically loaded components such as propeller hubs, gears, bushings, and pump parts.
