White Fused Alumina abrasive and polishing

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

Quility index of White Fused Alumina

 Properties: Used aluminum oxide powder as raw material,it is made by smelting at high temperature in the EAF.

Features: the Al203 content is up to 98%, higher hardness and lower toughness than the brown corundum; a better cutting performance.

Usage: made of abrasive, suitable for grinding hardened alloy steel, high speed steel. Fine-grained flour is also used for precision casting.
