Chinese Professional Nodular Iron Shell Mold Casting - Malleable Cast Iron Sand Casting Product – RMC Foundry

The malleable cast iron castings are usually cast by green sand casting or resin coated sand shell mold casting processes at RMC casting foundry.

Cast irons are the ferrous alloys which have carbon contents of more than 2%. Though cast irons can have a carbon percentage between 2 to 6.67, the practical limit is normally between 2 and 4%. These are important mainly because of their excellent casting qualities. The gray cast irons, ductile cast irons (also called nodular cast iron or spheroidal graphite iron) and malleable cast iron are the three main cast iron in foundry.

The malleable cast iron has free carbon which is present in the form of nodules in the matrix of cementite and ferrite. This is achieved by first chilling the casting so that all white cast iron is formed, followed by a controlled heat treatment process so that some of the cementite is transformed to ferrite and nodules of free carbon. This material is more ductile than grey cast iron. This form is suitable only for components with very small section thicknesses since all white cast iron is to form the starting point for malleable iron.
