Magnesia Alumina and Magnesia Alumina Carbon Bricks are widely used in Electrical Furnace, Ladle Furnace, Ladle Refining Furnace, VAD and VD applications. These products outperform others due to their excellent corrosion and oxidation resistance, resistance to spalling and high hot strength, which makes it an ideal solution for the hot impact areas.
