Aluminium Oxide Blasting Media Brown Fused Alumina F24# F36# F60# F120# F220# for Brake Pads
1. Product Description of Aluminium Oxide Blasting Media
Brown aluminium oxide belongs to the family of artifical corundum,
the first grade one contains 95% Min Al2O3,in
brown color,so it is also called as brown fused alumina.
It select the high quality bauxite,iron feelings,coke as main raw
materials,then fused in high temperature over 2000
degrees,then Cooling crystallization by special technology,finally
screened into different size according to the clients’
requirements.
It has high hardness and good-self sharpness,lower cost,which is
widely used in many industry applications, it is also
called as ”The Teeth of Industry”.

5. How to judge thequality of brown aluminium oxide?
Color: High quality brown aluminum oxide is in dark brown,shiny
with good gloss
Cleanliness: good quality products has higher cleanliness,which can
be seen easily by naked-eyes or put it
into the cleanwater.
Particle size: It has uniform particle size and little impurities
for good quality one.
6.Why brown aluminium Oxie is widely used as one blasting media?
It contains 95% Al2O3 and angular shape,which provides high
hardness and good self-sharpness,then remove
the impuritis of workpieces easily and also generate new edges in
the continuous sandblasting process,finally
improve the blasting efficiency and low the product cost; In
addition, it can be used in multiple cycles compared
with glass beads,so it is one popular and high price/performance
ratio blasting media.
