White fused alumina is made from high quality Bayerprocessed alumina by fusing
in an electric arc furnace at high temperature.
It has high hardness and better cutting characteristics. It is suitable for manufacturing
of vitrified and resinoid tools, and for lapping, polishing and blasting.
White fused alumina electrically fused in arc furnace with 2000 above the temperature with
high grade processed alumina as raw material. White fused alumina is a white crystal,
It has higher hardness and slight lower toughness comparing with brown fused alumina. It is
also characterized by its high purity, ability of self-sharpening, better cutting, less heat
emit, high efficiency, good thermal stability, acid and alkali resistance.
White fused alumina is compact and suitable in making ceramic, the resin solidifying
grinding tool as well as the attrition, polishing, the sandblasting, the precision
casting and so on, the white fused alumina also can be used in making the high-duty
refractory.
White fused alumina for sandblasting abrasive is characterized in high hardness, big
specific gravity, good chemical stability and unique self-sharpening.
White fused alumina for sandblasting abrasive is processed by high quality corundum from
RuiShi Abrasive plant as raw material and utilized by unique advanced technology. It is
characterized by short grinding time, high efficiency, good returns, low price and so on. It is
also the ideal material for sandblasting and derusting, workpiece cleaning and polishing.
