Advantages of Using Bronze in Marine Propellers

Bronze serves a significant role in the naval industry’s machinery. In fact, the U.S. Navy utilizes nickel aluminum bronze in marine propellers because of its strength and resistance to corrosion.

Because a nickel aluminum bronze tube, as well as sheets, withstand the marine environment for long periods of time without losing their integrity, it is an ideal component for propellers. But this alloy boasts other advantages as well.

Efficiency

Nickel aluminum bronze maintains its smooth, machined surface even after several years of use. The performance of the propeller generally remains as high as it was when first employed, which also lends to fuel efficiency.

Design Functionality

Thanks to this metal’s lighter weight than manganese bronze, designers can create thinner sections and smaller shafts. This results in lower loading stresses on the tailshaft and bearings.

Notch Sensitivity Resistance

Even when notched, you can rely on nickel aluminum bronze to function. It doesn’t break down under impact, a quality that ensures a smooth running ship.

Ease of Maintenance

Unlike manganese bronze, nickel aluminum bronze propellers provide ample strength and durability to resist bending, wear, friction, and breaking, among other incursions. It can also resist stress corrosion. Because of these resiliencies, maintenance and repair is relatively easy.

The many benefits of nickel aluminum bronze continue to buoy its standing in the marine propeller market. Knowing the metal’s properties and advantages are important in choosing manufacturing material for a ship’s many components.
