DURALUM ® AB is an electric arc furnace product made from high purity Bayer process alumina and the product chemistry is like that of white aluminum oxide. Alumina Bubbles are formed from molten alumina, resulting in hollow spheres of low bulk density.
CUMI’s synthetic fused alumina produced by controlled fusion of special alumina with other raw materials ensure low bulk density (1.7 vs 2.9 g/cc) and high refractoriness (PCE of 18500C +). This material exhibits very low thermal expansion coefficient (7.2x 10-6 / 0 C) which makes it a perfect substitute for zircon sand in foundry appliion.
Brown fused aluminum oxide is a tough, hard material (Mohs hardness 9) with high strength, excellent wear and corrosion resistance and good thermal conductivity. Fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other appliions.
They are produced in electric arc furnaces by electro thermal fusion at temperatures around 2000 C. Regular brown fused aluminum oxide is manufactured by melting bauxite in electric arc furnaces. White fused aluminum oxide is made from alumina.
