TITGGI 19 LBS #80 Grit Aluminum Oxide Blast Media
This premium long-lasting aluminum oxide blasting media from TITGGI features brown fused aluminum oxide with a Mohs hardness of 9, enabling fast rust removal and surface etching on glass, granite, marble, ceramic, steel, and more. It is designed to endure longer cycles than silica-based media, offering cost efficiency over time. The product is marketed as eco-friendly with no free silica and 100% recycled blaster sand suitable for both wet and dry blasting.
TITGGI 8 LBS #80 Grit Aluminum Oxide Blast Media
This smaller bag repeats the same high-hardness brown fused aluminum oxide with a Mohs hardness of 9, designed for compact blasting setups. It provides fast cleaning and etching across metal and mineral surfaces and emphasizes longevity and eco-friendly manufacturing. Ideal for users needing portable media for touch-up work, cabinet procedures, or smaller blasting guns.
Industrial Mineral Supply Aluminum Oxide – 50 LBS
Premium brown fused aluminum oxide suitable for heavy-duty blasting. It cleans and etches many surface types, including glass, granite, marble, ceramic, and steel, and is noted for yielding a high-quality metal finish. The larger 50-pound quantity supports professional shops and ongoing projects, helping minimize reordering frequency while maintaining consistent performance.
HDURCIR Aluminum Oxide 14 LBS 100 Grit
HDURCIR’s 100-grit aluminum oxide medium offers a balanced option for medium to fine finishing. Weighing 14 pounds, it suits blasting cabinets and guns for removal of mill scale, paint coatings, and surface prep on stainless steel, aluminum, wood, and glass etching. The media is compatible with both wet and dry blasting workflows and emphasizes the Mohs hardness of 9 for durable performance.
striplus #120 Grit Aluminum Oxide – 4 LBS
The #120 grit from striplus is a fine aluminum oxide option with 99.5% purity, designed for professional sandblasting cabinets and machines. It features sharp, angular grains that strip rust and scale quickly, while leaving an even satin finish on metal, glass, stone, and plastic. The media supports multiple recycle cycles due to its toughness and high hardness, offering cost efficiency and consistent results.
Buying Guide: Key Purchase Considerations
- Grit range and finish goals: Coarser grits (e.g., #60–#80) remove coatings faster, while finer grits (e.g., #100–#120) prepare surfaces for coatings or give satin finishes. Choose based on material hardness and desired final surface texture.
- Hardness and material compatibility: Aluminum oxide typically rates around Mohs 9, making it suitable for metal, glass, stone, and ceramic. Consider the substrate and any coatings to avoid excessive material loss or substrate damage.
- Bulk vs. small-pack options: Larger bags offer lower per-pound costs and are suited for shop environments with frequent blasting. Smaller packs are ideal for occasional users or trials.
- Wet vs. dry blasting: Some products specify compatibility with both wet and dry processes. Wet blasting can reduce dust and improve cooling, while dry blasting is often faster for batches.
- Environmental and safety considerations: Look for products with minimal free silica and eco-friendly production practices. Always use proper PPE and ventilation when blasting.
- Longevity and cost-per-use: Media that resists breaking down reduces frequency of replacement and lowers overall job costs. Recyclability is a plus for long-term projects.
- Equipment compatibility: Verify your blasting cabinet, gun, or machine’s media size and flow compatibility to ensure optimal performance and minimize clogs.
- Brand reliability and transparency: Consider brands with clear hardness specs, purity levels, and compatibility notes. This helps predict performance across different surfaces.
