White Corundum JIS/White Fused Alumina/Wa Abrasive
White Fused Alumina Description
White Fused Alumina is a high purity, synthetic mineral,manufactured by the fusion of controlled quality pure grade Bayer Alumina in an electric arc furnace at temperatures greater than 2000C followed by a slow solidification process. Strict control over quality of raw materials and fusion parameters ensure products of high purity and high whiteness,high hardness, toughness is a bit low, excellent self sharpening, grinding force, low calorific value, high efficiency,acid and alkali resistance, good thermal stability.
