TITGGI #100 Grit Aluminum Oxide Blast Media (8 LBS)
The TITGGI 8 LBS 100 Grit aluminum oxide blast media is described as a high-hardness brown fused aluminum oxide with Mohs hardness near 9, suitable for removing rust and etching a range of surfaces including glass, granite, marble, ceramic, and steel. Its long life is highlighted as a key advantage, with a claim that it lasts about 10 times longer than silica, reducing replacement frequency. The media is marketed as eco-friendly with no free silica and is suitable for wet or dry use, aligning well with both blasting cabinets and portable blasting setups.
TITGGI #100 Grit Aluminum Oxide Blast Media (12 LBS)
This larger TITGGI option provides 12 pounds of 100 grit media with similar attributes: high hardness for effective cleaning and etching, extended life compared with silica-based media, and eco-friendly composition with no free silica. It is suited for both metal preparation tasks and blasting cabinet work where longer run times matter for efficiency.
HDURCIR Aluminum Oxide 14 LBS 100 GRIT
HDURCIR offers a 14-pound bag of 100 grit aluminum oxide with a Mohs hardness near 9. It is positioned for use in blasting cabinets or with blasting guns and notes that the media is suitable for removing mill scale, paint coatings, and general surface preparation of stainless steel, aluminum, and wood, as well as etching glass. The larger bag size can improve cost efficiency per project.
Industrial Mineral Supply Aluminum Oxide 100 Grit
This 100 grit media from Industrial Mineral Supply emphasizes versatility for sandblasting, surface preparation, and precision engraving. It uses high-grade aluminum oxide particles for hardness and durability, suitable for cleaning, deburring, and creating textured finishes on metal, glass, stone, and other hard surfaces. The product is positioned as a reliable choice for consistent performance across tasks.
INTERACTIVIA #100 Aluminum Oxide – 12 LBS
INTERACTIVIA markets a 12-pound bag of 100 grit aluminum oxide with a focus on hardness, longevity, and non-reactivity. The listing notes no crystalline silica, matching concerns about worker safety and clean finishes. The grit is described as sharp and angular for efficient cutting, with tenfold life improvement over silica, making it a practical option for repeated blasting cycles.
INTERACTIVIA #100 Aluminum Oxide – 8 LBS
This 8-pound INTERACTIVIA option offers similar attributes to the 12 LBS variant, including high hardness, long life, and non-reactive behavior during surface prep. It is suitable for blasting cabinets and guns, with benefits cited around efficiency and risk reduction due to the absence of crystalline silica.
INTERACTIVIA #100 Aluminum Oxide – 19 LBS
The 19-pound INTERACTIVIA option emphasizes long life, sharp angular grit, and high efficiency for larger job runs. As with other INTERACTIVIA listings, it notes the absence of crystalline silica and compatibility with multiple blasting setups, making it a flexible choice for varied workloads.
Buying Guide: Key Considerations For 100 Grit Aluminum Oxide Blast Media
- Hardness and material compatibility: Aluminum oxide at 9 Mohs is widely suitable for metal, glass, stone, and wood. Consider your target surface and whether etching, cleaning, or deburring is the primary goal.
- Form factor and bag size: Larger bags reduce cost per project, but balance with equipment capacity and storage. Weight options from 8 to 19 pounds cover small to large projects.
- Wet vs. dry use: Some media lists mention wet or dry use. Wet blasting can reduce dust and improve surface finish in certain applications, while dry blasting is typically simpler and faster for metals.
- Safety and composition: Check for low or no crystalline silica to minimize health risks and cleanup concerns. Eco-friendly claims can reflect reduced waste and processing footprints.
- Durability and life cycle: Media that lasts longer reduces replacement frequency and can lower operating costs, particularly in high-volume shops.
- Compatibility with equipment: Ensure the media size and hardness suit your blasting cabinet or gun system, as improper pairing can cause accelerated wear or suboptimal finishes.
- Cost vs. performance: Compare long-term performance, not just upfront price. A slightly higher-cost media with longer life may yield better value over time.
- Quality assurances: Look for brands that provide consistency in grit sizing and minimal contaminants, which helps achieve predictable outcomes across jobs.
- Environment and disposal: Recyclability and dust control can impact workplace safety and regulatory considerations in shop settings.
