Ferro Silicon Calcium Manganese is used as a deoxidizer, desulphuriser and an alloying element in steel. Ferro Silicon Calcium Manganese can be used as a substitute for Ferro Silicon and Ferro Manganese when added to make different types of steel. Silicon and manganese have a strong affinity for oxygen, and will act as deoxidizers. Whereas Calcium acts as desulphuriser in iron and steel melt.

Industries use Ferro Calcium Silicon alloy is also used for the non-metallic inclusions modification. The suspended solid inclusions of aluminium oxide are liquified by calcium. Calcium (Ca) transforms alumoinium oxide (Al203) into CaO: Al2O3). It also improves the material properties of steel. In the solidified steel, the calcium aluminates are undeformable which maintains the high isotropy of the material properties even after steel working.
