Ferro Silicon Strontium - 0.2-10mm Granules, Silvery Grey Alloy Additive For Enhanced Casting Performance, Low Impurity Content 0.1%

With a sole aim in delivering quality products, we are the prominent Exporter, Manufacturer and Supplier of Ferro Silicon Strontium in Anyang, Henan, China.
Characteristics:-
Ferro Silicon Strontium Inoculant ( FeSiSr ) mainly used as casting inoculant, strontium in ferrosilicon inoculant is one of the most effective promotion elements, when large undercooling degree, strontium has a special function, to reduce the number of eutectic group can reduce shrinkage, shrinkage defects of casting.

Application

Ferro Silicon Strontium Inoculant ( FeSiSr ) suitable for thin-walled or chilled sweet ash high sulfur cast has strong ink capabilities, but also for ductile iron ball to increase the number of ink, especially high corrosion resistance of nickel ductile iron (containing Ni14%, Cu6 %, Cr2%, Si1.5%) in addition, since it reduces white without significantly increasing the number of eutectic, especially for applications that require no casting dense loose, the water pressure resistance gray cast to good effect, strong ink and carbon Si-Ca of molten inoculant different allowable temperature is low, and calcium, the amount of aluminum is low, less shaped residue, no vacuum casting defects.
