White corundum polishing powder 280#-600#

 

Alumina white corundum grinding powder 3000 grit is made from high-quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. The white alumina produced in titling electric arc furnaces has the advantage of high bulk density and low porosity and good volume stability and thermal shock resistance. As one of the most commonly used corundum in the abrasive industry, White fused alumina has a long history in applications because of its high hardness, good self-sharpening advantages. By adopting high-quality grade materials, a strict quality control system, and developed production technology, HAIXU’s white fused alumina gets high purity, stable quality, and good distribution.

The micro-powder from Haixu Abrasives is acid-washed and gets water pickled, by this process, the white fused alumina powder is with better purity and better grit size distribution.

 

Characteristic:

The electrofused aluminum oxide powder for polishing has outstanding features including small crystal size, impact resistance. By ensuring the excellent purity, HAIXU Abrasive's product works very extraordinary well at sand blasting and raw material for abrasive tools. Users will get a multi-recycle experience and more durable performance.
