Products Description



Ultrafine aluminum oxide blast media are white, spherical aluminum oxide blasting media.

This product is primarily used for surface finishing, capable of polishing workpieces to achieve a matte surface brightness.

Compared to traditional blasting media, this product is smaller in size, with a minimum size of up to 5 micrometers.

Why is ultra-fine aluminum oxide an ideal blasting medium?

1. High Purity
Ultra-fine aluminum oxide contains Al₂O₃ more than 99.0% , which is highly pure, white in color, and does not contaminate the treated surface with impurities.

2. High Friability
Ultra-fine aluminum oxide is more fragile and breaks down quickly, exposing new edges on the surface, providing new aggressiveness during the blasting process, making it easier to achieve the desired blasting effect.

3. Recyclable
It has characteristics of high hardness and high toughness, and can be reused multiple times during the blasting process, making it an economical abrasive that can be recycled.

4. Minimal Iron Contamination
White aluminum oxide causes minimal contamination to the treated surface. It is an ideal blasting medium for applications that prohibit iron contamination.
