Key Advantages
Al₂O₃ ≥95%
The high alumina content ensures consistent hardness and grinding performance, making the product suitable for continuous industrial use.
01
Mohs Hardness ≥9.0
It maintains strong grinding capability when processing hard workpieces such as steel and castings.
02
Fe₂O₃ ≤0.20%
The low iron content minimizes iron impurities, making it ideal for applications that require high surface cleanliness.
03
True Density 3.85–3.90 g/cm³
The brown fused alumina grains possess excellent density, allowing them to withstand mechanical impact during sandblasting and grinding without premature failure caused by grain fragility.
04
Suitable for both rough processing and fine-grit finishing
With a size range spanning from 8 mesh to 220 mesh, the abrasive can be selected to match specific workpieces and processing stages, rather than relying on a single grit size for every operation.
05
Applications of Brown Fused Alumina Abrasive
Sandblasting
Used for rust removal, descaling, old paint removal, and surface roughening on steel, castings, and mechanical components.
Sand-blasted and polished castings
Primarily used for rough polishing, deburring, rust removal, and chamfering.
Metal Grinding
Suitable for rough grinding and general grinding operations on materials such as carbon steel, alloy steel, and cast iron.
Surface Treatment
By selecting appropriate grit sizes, brown fused alumina abrasive can be used for metal surface pretreatment and surface texturing.

Common Questions About Brown Fused Alumina Abrasive
What grit sizes are best for Brown Fused Alumina abrasive?
+
-
There is no single grit size that suits every application. The 8–36 mesh range is better suited for rough processing and heavy material removal; 46–120 mesh is suitable for general sandblasting and grinding; and 150–220 mesh is ideal for finer surface finishing. The final choice should be based on the specific requirements of your equipment and the workpiece.
Can your Brown Fused Alumina be used in automatic sandblasting equipment?
+
-
Yes, the appropriate grit size can be selected based on the equipment type and the sandblasting process. When ordering, we recommend providing details such as the sandblasting equipment model, nozzle size, and desired surface finish so we can help match the right specifications.
What should I do if I don't know which mesh size to buy?
+
-
You can simply tell us the workpiece material, the processing method, and the surface finish you wish to achieve. We can recommend a suitable grit size based on your application before confirming a price quote.
Can you provide a COA (Certificate of Analysis)?
