Mischmetal is widely used in the ductile iron foundry and production of Ferro Silicon Magnesium (FeSiMg)- inoculants, while Magnesium Ferro Silicon (MgFeSi) is one of the most important input in the manufacturing process of Spheroidal Graphite Iron and Speciality Grey Iron casting for achieving the desired levels of nodularity and microstructure. These castings are used in Railways, Automobiles and Engineering industries. 
Chemical composition :

Size available: 30 gr, 50 gr, 100 gr, 250gr, 500gr, 1kg gr, 3kg, 8kg per ingot, plastic wrapped and oil coated.

Application: Cerium and other rare earth elements effectively eliminate the harmful effects of other components. Cerium Mischmetal is added to nodularised iron, offering the following benefits: -
- Increased nucleating sites for graphite precipitation.
- Extended effect of the nodularisation treatment.
- Nullification of the harmful effects of any trace elements present in the base iron. 
- Control of graphite morphology from vermicular to nodular. 

To be highlighted that Mischmetal is widely used as the alloying additive in the ductile iron foundry and Ferro Silicon Magnesium(FeSiMg or MgFeSi). it is used as the alloying additive of Magnesium Ferro Silicon (MgFeSi), a nodulariser/nodulizer/nodularizer/nodulant/nodulizing agent used in manufacturing ductile iron. It improves the shape of graphite nodules and negates the effect of tramp element and sulphur, it is a good inoculants & nodularisers in foundry.  

Mischmetal can also be used as the alloying additive of a Zinc-Aluminium alloy named Zinc-5 % Aluminum-Mischmetal (Zn-5Al-MM) alloy, having a 95% Zn-5% Al-trace mischmetal (cerium, lanthanum), which is often used to be as the coatings for steel, to enhance the product life for certain applications.
