White Fused Alumina

to achieve high corrosion resistance

ALTUS is an electrofused products manufacturer. Our white fused aluminum oxide (Al2O3), otherwise known as white fused alumina, is obtained from the fusion of high purity alumina powder in an electric arc furnace. White fused alumina is one of the hardest mineral available which make it ideal abrasive material and it’s also recommended for refractory applications where chemical stability and purity is important. Our white fused alumina is available in many shapes and sizes from macrogrits to microgrits.
