C62300

Aluminum Bronze
CuAl10Fe3

An American duplex aluminium bronze with the addition of iron for added strength and to inhibit grain growth during hot working. C62300 is non-sparking and retains properties down to cryogenic temperatures.

C62300 is a balanced alloy, which exhibits a combination of good corrosion, plus oxidation resistance and it also retains mechanical strength and physical properties at moderately elevated temperatures.
