Nickel Aluminum Bronze (ASTM B271) Applications

There is a large market for Nickel Aluminum Bronze (ASTM B271) in naval applications, particularly for the submarine fleets of the world. The main applications are in seawater piping and valve systems, weapons handling, flexible couplings, sonar equipment, seawater external hatches, hydraulic valves and bearings, fasteners and sealing flanges, low noise propellers, propulsion equipment as well as periscope assemblies. These applications make use of some of the important properties of the nickel aluminium bronzes: good corrosion resistance, non-sparking, wear resistance, high strength and good impact properties.

The alloys also exhibit good anti-damping property, twice that of steel, which is important for submarines in suppressing sound for silent operations. Non-sparking and wear resistance become particularly important in weapons’ handling systems. The various grades with lower iron and nickel contents can be manufactured with magnetic permeability below 1.03 µ.
