Aluminum Bronze

Aluminum Bronze C62300

Specs: AMS 4635, ASTM-B-150
UNS# C62300

Aluminum Bronzes have high strengths (comparable to medium-carbon steel), high hardness in the as-cast state, and excellent corrosion resistance properties. They possess good anti-frictional characteristics and resist scaling and oxidation at elevated temperatures.

 

Aluminum Bronzes can be hot worked readily, and some grades possess good cold forming characteristics and respond to a form of precipitation hardening.

Details

Alloy C62300 (CuAl9Fe3) is a binary Aluminum Bronze containing copper, aluminum, and iron.

 

The addition of iron helps grain refining and increases the mechanical strength.

 

The Aluminum Bronze C62300 is a medium to high strength bronze, which offers the combination of good corrosion resistance in seawater and many acidic environments.

 

It has good ductility, is easily machined, and has wear and anti-galling properties where it finds use in aerospace applications.

 

As with most copper-based alloys, it also maintains its properties at cryogenic temperatures.

 

The alloy is easily hot worked and can be welded by MIG or TIG joining techniques.

Available shapes –  round
