Product Details

Product description:

WA abrasive aluminium oxide powder F400

White fused alumina was made from the 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 furnace has the advantage of high bulk density and low porosity and good volume stability and thermal shock resistance. As a most common 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, strict quality control system, developed production technology, HAIXU’s white fused alumina get a high purity, stable quality and good distribution.

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

Product Features:

· High hardness and dense particles. Single-particle roundness is good.

· The colour is pure white, no impurities, to ensure the wear-resistant layer or wear-resistant paper colour and transparency.

· Uniform distribution of particle size, single-particle shape consistent, with a small amount of wear-resistant effect.

· Excellent Chemical stability with high acid-alkali resistance, high-temperature stability.

· WA abrasive aluminium oxide powder is produced strictly according to FEPA and JIS standard, all products are tested and qualified before shipment.

· Low electrical conductivity; moderately-high thermal conductivity; good refractoriness and resistance to molten metals.
