What Is Walnut Shell Abrasive?
Walnut shell abrasive is made by cleaning, crushing, grinding, and screening the hard outer shells of walnuts into graded particles, from coarse grit to fine powder. The particles are tough but much softer than metal, so they remove paint, flash, carbon and grime while leaving the surface underneath intact. It is also called walnut media, walnut shell grit, and walnut blasting media.
Why walnut Blasting Media is used instead of sand
Garnet sand and other hard abrasives can scratch, etch, or distort delicate parts. Walnut blasting media is a gentle, silica-free alternative, so there is no silicosis risk from the media itself, and it is biodegradable.
Walnut shell vs plastic media
Both are soft media. Walnut abrasive media is natural, biodegradable, and good for polishing and non-etching cleaning. Plastic media is synthetic, more consistent, and generally lasts through more reuse cycles.
Walnut Shell Grade and Mesh Size Guide
| Grade (mesh) | Size (mm) | Typical use |
|---|---|---|
| 6/12 | 3.35-1.70 | Heavy paint and coating removal, non-skid surfaces |
| 12/20 | 1.70-0.85 | General blasting, graffiti and paint removal |
| 12/40 | 1.70-0.425 | General cleaning |
| 20/40 | 0.85-0.425 | Mold cleaning, engine parts, deflashing |
| 30/60 | 0.60-0.25 | Fine cleaning, brass and aluminium, tumbling |
| 60/100 | 0.25-0.15 | Polishing, fine finishing, delicate parts |
| 100-200 | 0.15-0.075 | Fillers, cosmetics, fine polishing |
Quick choice: coarse grades remove paint faster, and fine grades give a smoother finish. Send us your surface and the contamination to remove, and we will recommend the mesh. Confirm which grades you stock before publishing.
Properties and Features of Walnut Shell
- Soft but tough: about 3 Mohs, resists crushing better than most organic media.
- Non-etching: leaves no anchor pattern on metal.
- Biodegradable and renewable: a natural material with no silica dust.
- Low density: specific gravity 1.2-1.4, light and easy to handle.
- Works in wet and dry use and across a range of temperatures.
- Recoverable and reusable a limited number of times, depending on the job.
- Low cost compared with synthetic soft media.
Benefits of Walnut Shell
- Safe on delicate surfaces: no scratching, pitting, or warping.
- Quick cleaning: removes carbon, oil, grease, and paint efficiently.
- Silica-free: no silicosis hazard from the media.
- Eco-friendly: natural, biodegradable, and renewable.
- Good finish: leaves a clean, uniform surface ready for coating.
- Versatile: blasting, polishing, filtering, and filling with one material.
- Low cost per job for soft-substrate cleaning.
Walnut Shell vs Plastic Media vs Glass Beads vs Aluminium Oxide
| Media | Hardness | Origin | Reusable | Best for |
| Walnut shell | About 3 Mohs | Natural | Limited | Gentle cleaning, polishing, deflashing |
| Plastic media | 3-4 Mohs | Synthetic | Several cycles | Paint stripping, deflashing, delicate substrates |
| Glass beads | About 5-6 Mohs | Synthetic | Yes | Peening, cosmetic finishing |
| Aluminum oxide | About 9 Mohs | Synthetic | Yes | Etching, heavy cleaning |
Rule of thumb: choose walnut blasting media for gentle, low-cost cleaning and polishing of soft or delicate surfaces. Choose a harder media when you need an etched profile or faster stripping of thick coatings.
