Nickel Aluminium Bronze – Its Properties, Benefits, and Uses

nickel alluminum bronze

Nickel aluminium bronze (NAB) is an alloy composed of copper, nickel, and aluminium. It has a range of properties that makes it a popular choice for engineers and material scientists in a variety of industries. Let’s take a look at some of these properties and the potential applications for this alloy.

Benefits of Nickel Aluminium Bronze

Nickel aluminium bronze is highly corrosion resistant, making it ideal for use in marine environments. Its special corrosion-resistant properties are due to its high nickel content, which helps prevent oxidation when exposed to seawater or other corrosive materials. The alloy also has good strength and ductility, so it can be easily formed into complex shapes without compromising its durability. It also has excellent wear resistance and machinability, making it easy to work with when creating custom parts or components.

One of the most attractive features of nickel aluminium bronze is its low thermal expansion coefficient. This makes it ideal for use in applications where extreme temperature fluctuations are present, such as aerospace engineering or equipment used in oil refineries. Furthermore, the alloy’s low friction coefficient helps reduce wear on machines over time.

Properties of Nickel Aluminium Bronze

Nickel Aluminium Bronze is an alloy composed of copper, aluminium, and nickel. It’s a popular material for use in ships and other boats because of its superior corrosion resistance and high strength-to-weight ratio. Its thermal properties also make it resistant to fatigue, brittleness, and cracking over time. Nickel Aluminium Bronze can be machined or cold worked with the proper tools and has good welding characteristics if done correctly. With its versatile combination of mechanical properties, modern construction often utilizes Nickel Aluminium Bronze components in difficult to manufacture areas such as ship propellers and stern tubes.

Nickel Aluminium Bronze uses

Due to its unique combination of properties, nickel aluminium bronze can be used in many different industries and applications. It is often used as valve trim in ships and submarines due to its superior corrosion resistance. Additionally, it is commonly used in ship propellers, engine components, gears, bearings, locksets, pumps/valves/fittings/flanges/etc., electric motors, machine tools/jigs/fixtures/etc., and nuclear components such as fuel rods, structural elements like aircraft frames and landing gear components. Finally, the alloy is widely popular for use in industrial piping systems due to its ease of fabrication combined with its durability.
