Best Blasting Media: TITGGI #80 Grit Aluminum Oxide
The TITGGI #80 Grit Aluminum Oxide media is a premium long-lasting option with a Mohs hardness around 9. Brown fused aluminum oxide enables fast rust removal and etching on diverse surfaces including metal, glass, and stone. The media is designed to resist breakdown, delivering a longer cycle life—reported to last about 10 times longer than silica-based media. It is advertised as eco-friendly with 100% recycled content and is suitable for both wet and dry blasting, providing flexibility for different workflows.
Aluminum Oxide – 10 LBS – #120 Grit
This 10-pound bag of #120 grit aluminum oxide features angular particles and a hardness of 9 on the Mohs scale. It is suitable for precise cleaning and etching, and can be used in both wet and dry blasting. The finer grit provides a more conservative material removal rate, making it a good choice for finishing work on aluminum surfaces with minimal surface impact and reduced risk of dimensional change.
#100 Aluminum Oxide – 12 LBS
INTERACTIVIA’s #100 Aluminum Oxide media emphasizes longevity and efficiency. With a sharp angular grit and a Mohs hardness of 9, it cleans and etches many surfaces, including glass. The product emphasizes non-reactivity to coatings during surface prep and highlights a long lifespan—up to 10 times longer than silica. It is reusable and versatile for metal, glass, stone, and wood prep in blasting cabinets or with blasting guns.
#100 Aluminum Oxide – 8 LBS
This 8-pound INTERACTIVIA option provides a robust angular grit with high hardness. It is suitable for preparatory work on a wide range of surfaces, especially where coating compatibility and surface cleanliness are critical. The media claims strong longevity and minimal interference with coatings, while avoiding detectable crystalline silica, making it a widely used choice in workshops focusing on safety and performance.
#80 Aluminum Oxide – 8 LBS
This 8-pound batch of #80 grit aluminum oxide emphasizes longevity and reusability. As with other high-hardness media, it supports efficient cleaning and etching across glass, metal, and stone. The angular grit helps with more aggressive material removal, while the absence of crystalline silica aligns with safer dust profiles for a metal prep workflow.
Brown Corundum 12 LBS – 100 Grit
HDURCIR’s Brown Corundum media features 100 grit and 12 pounds per bag, offering cost efficiency in bulk purchases. It is suitable for both wet and dry blasting and is used for surface preparation of stainless steel, aluminum, and wood, as well as glass etching. Its Mohs hardness around 9 enables effective removal of mill scale and coatings without excessive substrate damage.
Aluminum Oxide 12 LBS – 100 Grit
This HDURCIR 12-pound option with 100 grit focuses on balanced material removal with a fine finish. It is suitable for detailed prep on aluminum and related metals, offering wet or dry blasting compatibility. The product highlights the media’s hardness and its ability to etch and clean surfaces while preserving base material integrity.
Buying Guide
Key purchase considerations for aluminum blasting media:
- Hardness and grit size: Higher Mohs hardness (around 9) enables faster removal but may be more aggressive on thin parts. Finer grits (like #120) provide smoother finishes, while coarser grits (#80) remove more material quickly.
- Specialty chemistry: Aluminum oxide media is widely compatible with aluminum and multi-material surfaces. Look for non-reactive media that won’t interfere with coatings during subsequent finishing steps.
- Wet vs dry blasting: Wet blasting reduces dust and can improve surface finish; dry blasting tends to be faster and more cost-effective for general purposes.
- Reusability and lifecycle: Longer-lasting media reduces replacement frequency and total cost, especially in high-volume shops. Consider media with strong cycle life claims versus baseline silica products.
- Environmental and safety considerations: Media free of crystalline silica lowers health risks. Check for eco-friendly or recycled-content claims when evaluating options.
- Cost efficiency: Bulk bags or multiple-pounds-per-bag options can lower per-pound costs. Balance upfront cost with expected lifespan and performance in your application.
When selecting blasting media for aluminum, consider the exact surface outcome you need—whether a strong deburring, rust removal, or a fine etch finish—and balance it against your equipment’s capabilities and your safety protocols. The items listed above cover a spectrum of hardness, grit, and packaging sizes to accommodate hobbyist and professional setups alike.
