Product Description

          High Purity Brown Fused Alumina Powder Grinding Abrasive Materials

Product Description

Brown Fused Alumina For Abrasive.Cooled and smelted under an electric arc at a high temperature above 2000 degrees, brown fused alumina for abrasive is composed of quality bauxite, anthracite and iron filings. Normally, the brown fused alumina for abrasive will be crushed into shape by jaw crusher and ball mill. After magnetic separation, it will be screened into many kinds.  brown fused alumina for abrasive has a dense texture and it has a high hardness of 9 Mohs.

Product Feature

Brown Fused Alumina For Refractory Advantages:
1) No burst,no pulverization and crack in the using course of refractory
2) Refractory temperature is more than 1900°C
3) High quality bauxite as raw material
4) Low coefficient of linear expansion
5) Very low amount of iron oxide
6) High purity

Brown Corundum For Abrasive Sandblasting Precision Casting Advantages:

1) Very low amount of iron oxide, suitable for non-ferrous blasting operations.

2) Not affecting the color of the processing cases.
3) Sandblasting in the non-iron process.
4) High speed processing.
