Aluminium Bronze

Aluminium bronzes are the most widely used of all the high performance copper alloys, recognised as a versatile, high strength, corrosion resistant alloy particularly in subsea environments.

One of the most tarnish resistant of all the copper alloys, the appearance aluminium bronze does not deteriorate when exposed to the effects of atmospheric corrosion.

Used primarily in subsea environments, aluminium bronzes are increasingly being used in a variety of markets including chemical and petrochemical plants, power generation (including nuclear), desalination plants, aircraft and automotive engineering, marine and offshore, building and construction and general engineering.

General Information for Aluminium Bronze

Aluminium Bronze Groups

The four major groups of Aluminium Bronze are:

  1. Single-phase alloys containing less than 8% Aluminium.
  2. Two-phase (duplex) alloys containing 8 to 11% Aluminium. These alloys also frequently have additions of Iron and Nickel to increase strength. This group contains casting alloys AB1 and AB2, the wrought alloys CA105, CA104 and Defence Standard (formerly Naval Engineering Standard NES 747 when cast and the wrought form NES 833).
  3. Aluminium-Silicon alloys with low magnetic permeability
  4. The Copper-Manganese-Aluminium alloys with good castability.

Aluminium Bronze Weight Calculator

All weights shown using this metal weight calculator are for guidance only. They are calculated using nominal dimensions and scientifically recognised densities. Please note that in practice, the actual metal weight can vary significantly from theoretical weight due to variations in manufacturing tolerances and compositions.
