iron. Two more types of cast irons are also widely accepted as separate class owing to their achieved property. Thus, malleable cast iron derives its name from its ability to bend or undergo permanent deformation before it fractures. Malleable cast iron is produced by heat-treating (malleablizing) a white iron casting.
