Applications:

Malleable cast irons are often used as the material of choice for small castings or castings

with thin cross sections which, in other irons, would tend to have chill (carbides in the surface

layers due to the rapid cooling rates in thin sections).

Castings of less than a gram in weight are successfully sand cast in malleable cast iron. Another significant aspect is that the malleable properties can exist to the surface of the casting as opposed to in ductile irons where the cast surface can contain flake graphite, creating a situation where thin malleable iron castings can be stronger than ductile iron.

Malleable cast irons ability to be welded to other ferrous materials makes it ideal for complex brackets that need to be integral to steel castings or fabrications. Because all malleable cast irons are annealed, machinists can be confident not to encounter carbides leading to expensive tooling damage.
