1)It is composite alloy composed of silicon，calcium,and iron.It is the ideal composite deoxidizer and desulfurizer,for production of high-quality steel, mild steel,stainless steel, nickel alloy,titanium alloy,and other special alloy.It is suit for temperature improver for converter steel smelting,inoculant for cast-iron,additive for ductile iron.

4)Performance: Nature Block, Silver sheen. Both calcium and silicon have strong appetency with oxygen.

5)Chemical composition of Silicon Calcium: Ca,Si,C,Al,P,S

6)Application: It is quite ideal deoxidizer and desulfurizer. Silicon alloy not only have strong deoxidation ability, easy-to-discharge,but also can improve plasticity and fluidity of steel.  At present, it is used in high-quality steel, special steel and special alloy production, for end deoxidation, substitute for aluminum. It is suit for temperature improver for converter steel smelting, inoculant for cast-iron, additive for ductile iron.
