brown fused alumina dull sandblasting abrasive grain

Sandblasting aluminum oxide grain, brown corundum, brown aluminium oxide, dull grain shape, top high toughness

Description:

AETL is a very tough brown fused aluminum oxide abrasive with medium titania, blocky shape and high density. To get the kind of grains, we specially process the ingots, separate the magnetic material, and sieve the grains carefully to get a complete range of grit sizes. It is used for making vitrified bonded abrasive products where the very tough, strong aluminum oxide is required.

Applications:

AETL is used for making vitrified bonded grinding wheels. The tough, strong aluminum oxide characteristic also enable this abrasive the used for pressure blasting and surface finish.
