Material
Aluminum Oxide Abrasive Nylon
Abrasive-filled polyamide filament
Aluminum oxide abrasive nylon gives a gentler, more controlled cut than silicon carbide. It is chosen for finishing, cleaning and light deburring, especially on steel, where an even finish matters more than speed. On heavy scale or large burrs it can be too slow.

What is aluminum oxide abrasive nylon?
Nylon filament loaded with aluminum oxide grit, about Mohs 9, distributed through the filament so it cuts with both side and tip as it flexes. Filament runs from about 0.20 mm to 1.8 mm, with grit from about 46 to 600.
Where is it used?
In our range: the 120 mm P320 aluminum oxide cup brush on a 6061 aluminum hub, the 20 mm P320 aluminum oxide tube brush, glass processing brushes and ceramic glaze line disc brushes.
Why choose it over silicon carbide?
Aluminum oxide is tougher and less sharp, so it wears more evenly and leaves a finer, more consistent finish, and it is less likely to over-radius edges. It is the better choice for satin finishing, blending and light deburring on steel. Silicon carbide is better where the cut has to be fast or the material is very hard.
How hot can it run?
The carrier is nylon, rated about 90–120°C continuous. Use light pressure and the recommended speed so friction does not soften the filament.
What should you tell us?
The material, the finish you need, the brush form and size, and the machine and speed. Send a sample part with the finish you want if you have one.
Questions buyers ask about Aluminum Oxide Abrasive Nylon
When should I use an aluminum oxide abrasive brush?
For finishing, blending and light deburring where an even finish matters more than speed, especially on steel.
Why is my aluminum oxide brush cutting slowly?
It is a gentler mineral. For heavy scale or large burrs, use a coarser grit, a thicker filament, or silicon carbide or wire.
What is P320 grit used for?
Fine finishing: a smooth, even surface after deburring or blending with a coarser brush.

Heat Exchanger Tube Cleaning
A heat exchanger tube is judged by how much clean wall it gets back, because even a thin layer of scale or biofilm costs heat transfer.

Surface Finishing
In surface finishing the pattern the brush leaves is the product, so fill, grit, speed and direction belong in the specification.

Polishing
A polishing brush or buff carries compound against the surface and removes a very thin layer, taking out fine scratches, haze and oxide film.
