Al2O3>99% (White Alumina) - SURPREX AW


Fujimi's line of Aluminum Oxide (Al2O3) thermal spray materials are fused and crushed Al2O3 powder. Our aluminum oxide is a single crystal α - Al2O3 with blocky shape particles. We can supply aluminum oxide with relatively low-cost, excellent flowability while preventing black spots on the surface of aluminum oxide coatings.

There are many types of standard White Aluminum Oxide, purity > 99.6% available today.
