A highly ductile wrought nickel-free aluminium 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. It meets the requirements of ASTM B 150 C61300 (bars) and ASTM B 171 C61300 (plates).
ASTM B 171 C61300
ASTM B 100 C61300
A single phase ductile aluminium bronze with the addition of tin to give excellent corrosion resistance and low magnetic permeability.
C61300’s ductile properties mean it can be cold worked, making it the perfect alloy for components such as:
The addition of tin gives added corrosion resistance.
