Product Description:
Silicon metal 553 is widely used in refractories, it is an excellent antioxidant. Adding silicon metal 553 in the refractory material can first react with oxygen to form a new mineral phase, close the pores, improve the density, prevent the penetration of slag iron, so as to improve the product’s high temperature resistance, wear resistance and oxidation resistance of the product.
The number 553 represents the content of Ferrum, aluminum and calcium in it. The shape of silicon metal 553 includes natural block, standard block, granules, powder etc. It can be customized to different shapes according to customer’s requirements.
In the actual production of aluminum ingots, silicon metal 553 can be quickly dissolved in aluminum water, improve the mechanical properties of aluminum, so that aluminum has a really good plasticity.
