Nimag [Pty] Ltd manufactures a comprehensive range of "Metalloy" Nickel Magnesium and other Master Alloys for use in processes requiring the efficient nodularisation of graphite to produce Spheroidal Graphite [SG] iron, as well as desulphurisation and other metallurgy using magnesium or calcium as the scavenger:

HIGH MAGNESIUM CONTENT ALLOYS

Metalloy NiMag Alloys
Manufactured using a range of selected raw materials including magnesium [typically 16%] to maximise efficiency and to limit flare.

Metalloy NiMSil Alloys
Specifically manufactured to include an effective 30% Silicon to assist with innoculation during the process Deoxidation, Desulpurisation and Nodularisation.

Metalloy FeNiMag Alloys
Carefully formulated to include high grade Iron, to reduce Nickel content and cost, yet maintain slow Magnesium release and high Alloy density.

LOW FUME ALLOYS

Metalloy FeNiMag 4
A relatively new product designed to maximise Alloy density to greater than that of the melt and ensure controlled release of magnesium into the bottom of a ladle to induce nodularisation. It is also used to prevent fade, should pouring be delayed.

Metalloy 95/5 Alloys
High Nickel and tightly controlled Magnesium containing Alloys designed for those melts requiring high Nickel concentrations and virtually no visible fume.

Metalloy NiCal Alloys
The active ingredient of Magnesium is replaced by Calcium, considered to be one of the best Desulphurisers and Deoxidisers, offering a calm treatment and minimum fume.

SPECIAL ALLOYS

Metalloy CuMag Alloys
Specialised Copper Master Alloy used in the manufacturing of Copper tolerant Nodular Irons and in particular compacted Graphite.

Metalloy Ferro Nickel Shot or Pellets
Low melting point form of unwrough Nickel produced as a Shot for Shot Blast or in a Pellet shape for ladle addition of Nickel.

Other Metalloy Alloys
NiCrB 3%, Monel H, Monel 400, and other specialised Master Alloys produced to customer requirement
