Double Spiral AO Abrasive Tube Brush | Aluminum Alloy Deburring Soft Metal Finishing

Product Name:
Double Spiral AO Abrasive Tube Brush (Aluminum Oxide Abrasive Filament)

Product Size:
Customizable according to customer requirements

Material Composition:

• Filament Material: Aluminum oxide (AO) abrasive-filled nylon filaments

• Handle/Stem Material: Steel (twisted wire stem)

Product Features:

• Aluminum oxide abrasive provides slightly lower hardness than silicon carbide, resulting in smoother cutting action and reduced risk of over-cutting

• Double spiral structure ensures uniform contact and consistent material removal across the tube interior

• Excellent surface finish – ideal for scratch-free treatment on softer metals

• High elasticity bristles conform to irregular inner wall surfaces

• No bristle loss & falling off – safe for precision assemblies

• Long service life with stable abrasive performance

• Particularly suitable for aluminum alloy and other soft alloy deburring

Applicable Scenarios:

• Automotive parts manufacturing & machining – as widely used as silicon carbide brushes for engine components, transmission housings, and aluminum castings

• Metal deburring & chamfering on aluminum alloy parts in aerospace and home appliance industries

• Precision aperture grinding for hydraulic valve blocks and compressor components

• Metal tube inner wall treatment on soft metal pipes

• Solve metal part burr problems without damaging the workpiece surface

• Improve part surface smoothness on aluminum, brass, copper, and other non-ferrous alloys

Comparison with Silicon Carbide (SiC) Abrasive Tube Brush

Unlike our standard Double Spiral Silicon Carbide Abrasive Tube Brush which offers higher hardness for aggressive cutting on ferrous metals and hardened surfaces, the AO (Aluminum Oxide) version delivers a smoother, more controlled cutting action. This makes it the preferred choice for:

For customers working primarily with aluminum alloy parts in automotive or aerospace industries, this AO double spiral tube brush offers the perfect balance between high deburring efficiency and non-destructive surface treatment.

Why Choose This Brush?

Standard steel tube brushes may scratch or gouge soft aluminum surfaces. Our double spiral AO abrasive tube brush solves this problem by providing consistent abrasive action that removes burrs without damaging the base material. It is widely used in automotive parts manufacturing for cleaning and deburring aluminum castings, as well as in precision engineering parts finishing for soft alloy components.
