Aluminium Bronzes

Aluminum bronzes are used for their combination of high strength, excellent corrosion ,toughness and wear resistance.

Aluminum bronze alloys typically contain 9-12% aluminum and up to 6% iron and nickel.

Aluminum bronzes are used in marine hardware, shafts and pump and valve components  for handling seawater,  sour mine waters, non oxidizing acids, and industrial process fluids.

They are also used in applications such as heavy duty sleeve bearings, and machine tool ways.

They are designated by UNS C60800 through C64210.

We supply a variety of Aluminium Bronze Welding Alloys  to suit above mentioned applications.
