White Fused Alumina Abrasives is classified to exacting standards for various applications where higher purity levels and reduced iron content are required.
White Fused Alumina is produced by fusing calcined alumina. It is white in colour, a dense mineral and has predominantly large crystals of Alpha Alumina.
White Fused Alumina 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.
Description of White Fused Aluminum Abrasives
White fused alumina is fused by alumina powder by electric arc furnace under high temperature. It has white color and little higher hardness and lower toughness comparing with brown fused alumina. The micro hardness of the product is 2200-2300kg/mm2. White fused alumina has higher hardness and slight lower toughness comparing with brown fused alumina. White fused alumina is also characterized by its high purity, acid and alkali resistance, good thermal stability. It’s the high grade refractory materials.
Applications of White Fused Aluminum Abrasives
Dedicated lines produce products for different applications. White Fused Alumina is highly friable and hence used in Vitrified Bonded Abrasives products where cool, fast cutting action is essential and also in the manufacture of high purity Alumina refractories. Other applications include use in Coated Abrasives, Surface treatment, Ceramic Tiles, Anti-Skid Paints, Fluidized Bed Furnaces and Skin / Dental Care.
