HDURCIR Aluminum Oxide 80 Grit – 14 LBS
Best for heavy-duty rust removal and aggressive paint stripping. This 14-pound bag uses aluminum oxide with a Mohs hardness of 9, suitable for blasting cabinet or guns. It can be used wet or dry, making it versatile for workshop setups. Suitable for metal surfaces like stainless steel and aluminum, as well as wood and glass etching. Choose this when you need a cost-effective, high-volume media for frequent blasting sessions.
- Best for: heavy removal tasks, general-purpose metal prep
- Why selected: cost-effective large packaging, compatibility with wet/dry blasting
- Caution: ensure proper ventilation and PPE when using in enclosed cabinets
HDURCIR Aluminum Oxide 100 Grit – 14 LBS
Better for smoother surface prep and finer finish on stainless steel, aluminum, and wood. The 100 Grit package shares the same hardness and wet/dry usability as the 80 Grit, but with a finer particle size for less aggressive material removal. Prefer this when a cleaner finish is required before coatings or paint.
- Best for: intermediate finishing, coating prep
- Why selected: balances material removal with surface smoothness
- Caution: may require longer blasting time on tougher coatings
TITGGI #80 Grit Aluminum Oxide (19 LBS)
This premium 80 Grit media is designed for long wear and strong performance. Brown fused aluminum oxide provides hardness near 9 on the Mohs scale, effective for rust removal and etching on glass, granite, marble, ceramic, and steel. It lasts longer than many alternatives and is suitable for both wet and dry blasting. Best for heavy-duty projects where durability matters.
- Best for: long-lasting performance, rust removal on hard surfaces
- Why selected: higher volume per bag reduces reordering frequency
- Caution: heavier media may require more containment and dust control
TITGGI #80 Grit Aluminum Oxide (8 LBS)
Compact option for small shops or precision work. The 8-pound bag provides the same high hardness and eco-friendly profile as larger TITGGI media, with the advantage of easier handling and storage. Best for detail work, touch-ups, or projects with limited blasting space.
- Best for: small projects, precision prep
- Why selected: convenient package size
- Caution: higher cost per pound vs. larger bags, not ideal for big jobs
INTERACTIVIA #120 Aluminum Oxide – 8 LBS
Fine 120 Grit media suited for finishing and polishing. It cleans and etches various surfaces, including glass, without introducing crystalline silica. The 8-pound bag is ideal for projects requiring a finer finish or pre-coating preparation. Best for: glass etching and gentle surface prep.
- Best for: fine finishing, glass work
- Why selected: no detectable crystalline silica
- Caution: finer grit removes material slower than coarser options
Buying Guide
Key considerations when choosing aluminum oxide blasting media:
- Project goals: Remove coatings quickly vs. achieve a smooth finish. Coarser grits (80) remove faster; finer grits (120) finish better.
- Substrate compatibility: Metal surfaces tolerate higher aggression; glass and wood may benefit from finer grits.
- Dry vs. wet blasting: Wet blasting reduces dust and can improve finish; ensure equipment compatibility.
- Media lifespan: Longer cycle life reduces replacement frequency but may cost more upfront.
- Health and safety: Use appropriate PPE; avoid free silica and ensure proper ventilation in enclosed spaces.
- Package size: Large bags provide economy of scale for shops; smaller bags suit limited workflows or testing.
Practical comparison tips
- For heavy coating removal: choose 80 Grit media with high hardness and larger mass per bag.
- For refined surface prep before coatings: select 100–120 Grit media to minimize surface roughness.
- For delicate pieces or glass: prefer finer grits (120) to minimize pitting while achieving a clean surface.
Frequently Asked Questions
- What is aluminum oxide blasting media best used for? It is ideal for cleaning and etching a variety of surfaces, including metal, glass, stone, and wood, with high hardness and durability.
- Can aluminum oxide be used wet and dry? Yes, many formulations support both wet and dry blasting, depending on equipment and job requirements.
- Is aluminum oxide safer than other blasting media? It generally lacks crystalline silica and is considered safer when proper PPE and ventilation are used.
- How do I choose the grit size? Coarser grits remove material faster; finer grits provide smoother finishes and less aggressive cleaning.
- Will media degrade quickly on hard metals? Aluminum oxide media has a long cycle life, often outperforming silica-based media in durability.
- Are there eco-friendly options? Some formulations emphasize recycled content and no free silica for environmental considerations.
