TITGGI #80 Grit Aluminum Oxide Blast Media
The TITGGI media presents a high-hardness brown fused aluminum oxide with a Mohs rating near 9, just below diamond. It specializes in fast rust removal and etching on metals, glass, granite, marble, ceramic, and steel. The product claims a long cycle life, lasting significantly longer than silica-based media, which can reduce replacement frequency and overall costs. It is described as eco-friendly and suitable for both dry and wet blasting. This makes it a versatile option for metal prep where precision matters and surface integrity must be preserved.
INTERACTIVIA #120 Aluminum Oxide (8 LBS)
INTERACTIVIA offers a 120 grit aluminum oxide that executes sharp, angular cutting action. The media is described as longer-lasting and highly reusable, with clean performance that avoids reactive interference with coatings during surface prep. It emphasizes absence of detectable crystalline silica, which supports safer handling and cleaner media. This option is well-suited for fine surface preparation on glass, metal, and other hard surfaces where a satin or smooth finish is desired after rust removal or coating removal projects.
HDURCIR Aluminum Oxide 14 LBS 100 GRIT
HDURCIR presents a 14-pound pack at 100 grit, offering a cost-effective option for larger jobs while maintaining the Mohs hardness of 9. The media is suitable for wet or dry blasting and is positioned as effective for removing mill scale and paint coatings, as well as preparing surfaces of stainless steel, aluminum, and wood. The large package size appeals to workshops with frequent blasting tasks and helps reduce the frequency of repurchasing media.
striplus #120 Grit Aluminum Oxide (4 LBS)
striplus offers a 4-pound pack of #120 grit aluminum oxide with 99.5% purity and high hardness. The sharp, angular grains are said to strip rust, paint, and scale quickly, leaving an even satin finish on metal, glass, stone, and plastic. The media is described as reusable, with potential for 6–8 cycles, which can reduce per-job abrasive costs. This makes it a good option for precision work and smaller projects requiring consistent finish quality.
HDURCIR Aluminum Oxide 12 LBS 100 GRIT
This HDURCIR option features 12 pounds of 100 grit aluminum oxide, designed for both dry and wet blasting. It emphasizes the Mohs hardness of 9, suitable for removing mill scale, coatings, and for surface preparation of stainless steel, aluminum, wood, and glass etching. The larger bag size makes it a practical choice for shops that tackle a variety of metals and require consistent performance across multiple sessions.
HDURCIR #10 Glass Beads (10 lb) for Blasting
While not a pure aluminum oxide media, glass beads offer a different blasting profile focused on a gentler, spherically rounded finish. This 10-pound option is useful for decorative finishing, peening, or cleaning softer substrates without heavy material removal. It provides a distinct alternative for projects that require less aggressive abrasion and a brighter surface, especially on softer metals and glass.
Buying Guide
- Grit range and surface goal: Coarser grits (e.g., 80) remove material quickly and create a rough profile, while finer grits (e.g., 100–120) produce smoother finishes suitable for coating preparation.
- Hardness and longevity: Aluminum oxide typically ranks around Mohs 9, delivering strong performance and durability. Media life directly impacts cost per job, especially in high-volume shops.
- Wet vs. dry blasting: Some media support wet blasting, which can reduce dust and heat buildup, while others are optimized for dry blasting. Consider your equipment and substrate sensitivity.
- Coatings compatibility: Media should be compatible with coatings and avoid introducing reactive elements that could affect adhesion or cure.
- Safety considerations: Choose media with low crystalline silica content when possible to minimize respiratory hazards. Use proper PPE and ventilation in blasting environments.
- Package size and workload: Larger bags are cost-efficient for frequent blasting, while smaller packs are convenient for small or specialty jobs.
- Surface finish needs: For a satin finish on metal or glass etching, finer grits and controlled blasting conditions work best. For rust removal and heavier coating removal, coarser grits may be appropriate.
