Product Description
low price sand blasting grit abrasive grit for sandblasting machines
Brown Aluminum Oxide powders are fused with premium raw materials and 3500 KVA furnace. It is perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, polishing and sandblasting grit. While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials. It is also be used as high-class refractory materials. Brown aluminum oxide is offered in macro and micro powder form, in both F and P grades.
Refractory grade:1-0mm,3-1mm,5-3mm,5-8mm -200mesh,-240mesh,-320mesh

Main Features of brown fused alumina and white fused alumina powder
Both basic mineral: a-al203
Both Ph value: Neutral
Both Max usable temperature in air is 1900 Celsius degree, decomposition pointis 2250 Celsius degree.
Both main chemical composition of finished products are: Al203
Both main applications are: in refractory and abrasives products.
Both Mohs hardness are: 9.0
Differences are below:
BFA bulk density is(1.53-1.99g/cm3)and true density (3.90g/cm3). While WFAbulk density (1.75-1 95g/cm3)and true density (3.95-397g/cm3).
Main raw material of bfa is bauxite, and main raw material of WFA is calcinedalumina powder
BFA has al203 content of 95% Min, WFA has al203 Content of 99% MinBFA has refractory temperature 1850 Celsius degree, WFA has refractorytemperature 2100 Celsius degree.
Although their Mohs hardness is 9.0, WFA is even harder than BFA, and BFA ismore flexible than WFA
