This kind of Brown Fused Alumina is mainly used for various material workpieces to decontaminate, derusting, prevent corrosion, remove oxide skin, light- decorate , process pattern effect and so on. About Brown Fused Alumina for Sand blasting:
 There are three factors the decide the effect of Brown Fused Alumina for sand blasting :
1.The grinding ability: the higher grinding ability ,the better for sand blasting.
2.The bulk density: the higher bulk density ,the better for sand blasting.
3.The dust: the lower dust, the better for sand blasting.

Brown Fused Alumina with high bulk density and air cleaned,the quality of this kind of Brown Fused Alumina is very excellent for sandblasting.

 

 

Packing:1 MT big bag or 25kg paper bag *40 bags on one pallet ;
