Product Description

Black Fused Alumina

Black Fused Alumina is made using bauxite and iron oxide raw materials which have gone through a smelting process in a tilting arc furnace to ensure high-grade products. It has few impurities, high grade, and stable quality, making it suitable for producing grain-size sands and micro-powder with moderate rigidity, delicate tenacity, and excellent service performance. Widely used in abrasives, high-temperature processes, and wear-resistant coatings, it's an ideal choice for diverse industrial applications.
