There are two groups of malleable cast iron namely whiteheart malleable cast iron and

blackheart malleable cast iron. These two groups are differentiated by chemical composition, temperature and time cycles of the annealing process, the annealing atmosphere and the properties and microstructure resulting there from.


Whiteheart malleable cast iron – It is a decarburized cast iron. The microstructure of whiteheart malleable cast iron depends on section size.


Blackheart malleable cast iron – It is either ferritic or pearlitic. Ferritic blackheart malleable cast iron is softer and more ductile.
