C61300

Description

A highly ductile wrought nickel-free aluminum bronze with a nominal composition of CuAl7Fe2.5Sn. C61300 contains 2.5% iron, which facilitates added strength and acts as a grain refiner. C61300 also contains a small addition of tin, which aids corrosion resistance. The alloy is mainly produced in the form of plates for sea water applications and is also used in water condensing systems.
