Foundry Inoculant (FeSiSr)

FeSiSr

Strontium-bearing ferrosilicon inoculant (Si 73-78%, Sr 0.6-1.0%) for grey and ductile iron. Strontium delivers potent graphite nucleation at a low addition rate with minimal silicon pickup, so it controls chill in thin and section-sensitive castings without raising eutectic cell count the way barium grades can. The result is a clean, uniform graphite structure, fewer edge and core carbides, and steadier mechanical properties from shot to shot. Fade resistance is strong, which suits longer pour windows and stream or in-mould dosing. Supplied in 0.2-0.7mm and 1-3mm sizings with COA + MTC on every lot.
