Description
Norton R445 Silicon Carbide Abrasive Belts – Sharp Cutting Belts for Finishing Made to Your Size
The Norton R445 silicon carbide abrasive belt is a strong choice when you need a sharp cutting grain and a clean, consistent scratch pattern. Silicon carbide is commonly selected for non-ferrous metals, plastics, and finishing tasks where the abrasive needs to cut cleanly rather than “plough” the surface.
For users working on aluminium, brass, bronze, composites, or specific finishing stages, silicon carbide often delivers a more refined result than general aluminium oxide belts.
Use our Belt Calculator to order Norton R445 in custom belt sizes and select your grit to match your machine and finish target.
Why Choose Silicon Carbide (R445)?
- Very sharp grain for clean cutting on suitable materials
- Excellent finishing control with a consistent scratch
- Great for non-ferrous metals and many plastics/composites
- Useful for surface prep where finish quality matters
Best Applications
- Aluminium and non-ferrous finishing
- Plastics, composites, GRP and similar materials
- Surface preparation and fine finishing stages
- Process steps where a clean scratch pattern is required
Silicon Carbide vs Aluminium Oxide vs Zirconia
| Type | When to Choose |
|---|---|
| Silicon Carbide (R445) | Sharp cut, non-ferrous, plastics/composites, refined finishing |
| Aluminium Oxide | General sanding, wide use, good value |
| Zirconia | Heavy pressure metal sanding, longer life on steel |
