Nodularizers

NODULARIZER

Nodularizers 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.

Products We Manufacture

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.
