White Fused Alumina Product Description:
White Fused Alumina for Abrasive and Refractory belongs to the group of electro-corundum. It is produced by controlled melting of alumina in an electric arc furnace. White fused alumina is iron-free, ultra pure and extremely hard.
White Fused Alumina is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has predominantly large crystals of Alpha Alumina. Ingots are crushed, ground, and precision screened in our new sizing plant to obtain very consistent sized fractions. Magnetic iron from crushing is removed by rare earth magnets to ensure very low levels of iron in the finished products. Close sized fractions are available or precision blended to specification. This process ensures a very consistent sizing from coarse to fines which is critical in many applications.
White Fused Alumina Product Features:
White fused alumina is slightly higher than the brown fused alumina , toughness slightly, with its abrasive made for grinding high-carbon steel, high-speed steel and stainless steel fine-grained abrasive. Can also be used for precision casting and high-level refractory material.
