Inoculants & Nodulisers
Inoculants are added in Liquid Cast Iron in order to provide the best and consistent characteristics in the final casting. They are used to control matrix structure and avoid casting defects. Inoculants can be found under several grain size distributions to satisfy the location of the Inoculant addition within the foundry process. Those locations of Inoculant addition are known as In‐Furnace, In‐Ladle, In‐Stream or In‐Mould. Inoculants are Ferro‐Silicon based alloys. All elements which are Aluminum, Barium, Bismuth, Calcium, Carbon, Strontium, Zirconium or Rare Earth can be added in exact amount into the base liquid iron in order to provoke and certify the final casting matrix structure
Nodulisers are alloys with Silicon as main component and traces of Magnesium, Cerium; Calcium with specific relevance. The nodulisation process enables the transformation of lamellar graphite into spheroidal or vermicular one, thus improving mechanical strength, elongation and material resilience.

FERRO SILICON MAGNESIUM
Ferro Silicon Magnesium Alloy imparts the correct Graphite Structure required in S.G.Iron thereby improving the Tensile Strength & its elongation properties. We produce Ferro Silicon Magnesium in wide range of specifications & combinations of Magnesium, Calcium & Rare Earth. With bare minimum inclusions of Dross & Oxides, our material reduces Alloy consumption by giving maximum recoveries with reduced fume generations.
Stringent control of Chemistry and size is ensured by offering tailored specifications & size requirements for all applications processes such as In‐Mould, Tundish or Sandwich.
