Aluminum Bronze
CuAl8Fe3

An American low alloy nickel-free aluminium bronze where its unique combined properties of medium strength, high ductility, excellent corrosion resistance in salt water, makes it a popular choice for many commercial and defence marine applications.

C61400 aluminium bronze has higher ductility than the nickel aluminium bronzes and can be cold worked to significantly enhance the mechanical properties.

C61400 maintains its properties at low temperatures for cryogenic temperatures down to – 452 ºF (-269 ºC).

This is a precision wrought alloy that benefits from extreme consistency in properties, fine equiaxed grain structure and low cost volumetric inspection. Furthermore representative test pieces are taken giving accurate analysis of properties from material to component.
