Note: Chemical composition, size and packing of above mentioned products can be adjusted according to customer's requirements. Characteristics 1.Ferro Silicon Magnesium Alloy is shaped in gray lump with metal luster. It is solid and brittle so that it is easy to be smashed. 2.With stable reaction, the absorption rate of Mg. will be increased which is helpful for getting high-quality casting products. 3.High mechanical strength and strong deoxygenation and desulfuration effects.
