ferro silicon magnesium – Price, Specifications & Global Supply

ferro silicon magnesium (FeSiMg), commonly known as nodulizer, is a ferroalloy composed of silicon, magnesium, iron, and controlled levels of calcium, aluminium, and rare earth elements.

Standard FeSiMg grades contain 44–47% silicon and 5.5–6.5% magnesium, engineered for consistent nodularization performance in ductile iron (SG iron) production.

FeSiMg is supplied in lump form with a metallic grey appearance. Chemical composition, purity level, and grain size can be adjusted based on the buyer’s technical requirements.
