Silicon Aluminum Ferro alloy 

 

Properties

 

(1)High Quality SiAlFe alloy is a kind of complex deoxidizer. Its density is higher than the density of pure aluminum.

 

(2)It can easily integrate into molten steel and get a little burning loss in it.

 

(3)Its deoxidation effect is more than two times than pure aluminum’s in the process of making steel.

 

(4)After deoxidation, Ferro aluminum becomes the product which has low smelting point can float easily on the surface of the molten steel so as to reduce the inclusion in the molten steel to improve quality of the molten steel.
