WHITE FUSED ALUMINA FOR SANDBLASTING
White Aluminum Oxide, code WA, is an ultra-pure, iron-free
abrasive, made of industrial alumina powder as raw material and
Fused in an electric arc furnace at 2000 degrees temperatures, then
cooled and pulverized and shaped to remove iron by magnetic
separation.
It has brilliant white color, extraordinary hardness, and sharp
edges. Highly resistant to corrosion, chemical stability, high bulk
density and low porosity give it extraordinary volume stability and
thermal shock resistance. It can be crushed and sieved to a wide
ranges of sizes, from large grains to micro-powders, and is widely
used in abrasives, blasting, polishing and refractory.

FEATURES IN SANDBLASTING
The advantages of white aluminum oxide in sandblasting
1. It does not affect the original color of the processed parts.
When using other abrasive, it is easy to cause blackening and
discoloration of the workpiece, which seriously affects the
appearance and is not easy to eliminate;
2. White aluminum oxide is the best sandblasting abrasive not to
remain iron powder on the workpiece;
3. White corundum powder is very suitable for wet sandblasting,
grinding and polishing operations;
4. White aluminum oxide has strong cutting force, also has good
chemical stability, so the sandblasting speed is fast and
efficient.
5. The color is pure white, no impurities, ensuring the color and
transparency of the wear layer.
Surface cleaning
Cleaning: metal parts such as castings, stampings, welded parts,
heat-treated parts, etc., descaling, residue, dirt; surface
cleaning of non-metallic products, removal of black spots on the
surface of ceramic blanks and reduction of lacquer patterns.
Especially for Aluminum alloy, zinc alloy workpiece blast cleaning
to scratch, squeeze lines, derusting, degreasing, descaling, etc.,
