TITGGI #80 Grit Aluminum Oxide Blast Media
The #80 grit aluminum oxide media from TITGGI is a high-hardness brown fused oxide rated at 9 on the Mohs scale, just below diamond. It’s designed to clean and etch diverse surfaces, including glass, granite, marble, ceramic, and steel, enabling fast rust removal and surface prep. The media is long-lasting and can be used wet or dry, offering a cost-efficient cycle life that outperforms silica-based options. It is also marketed as eco-friendly with no free silica and 100% recycled content, aligning with stricter quality standards for metalworking projects.
Key features: high hardness for aggressive cutting; extended life reduces replacement frequency; suitable for multiple substrates; wet or dry use; silica-free for safer handling.
TITGGI #120 Grit Aluminum Oxide Blast Media
The #120 grit variant from TITGGI also features brown fused aluminum oxide with a Mohs hardness of 9, designed for precise cleaning and etching across surfaces like glass, granite, marble, ceramic, and steel. With its long-lasting performance, it remains a cost-effective option compared to silica-based media. Its eco-friendly profile and ability to be used in both wet and dry blasting environments make it a versatile choice for projects requiring finer finishes or detailing work on metal parts and hardware.
Key features: robust hardness for durable results; longer life than many alternatives; eco-conscious composition; wet/dry compatibility.
Industrial Mineral Supply Aluminum Oxide (#220)
This premium brown fused aluminum oxide is rated #220 grit, positioned for a finer finish and smoother surface prep. It reliably cleans and etches a wide range of materials including glass, granite, marble, ceramic, and steel, delivering a refined metal finishing touch. The media’s finer size makes it ideal for achieving uniform textures and gentle deburring, especially on delicate surfaces or components that require tighter tolerances in preparation for coatings or welding.
Key features: finer grit for detailed finishing; versatile on multiple substrates; consistent performance; suited to high-precision prep tasks.
INTERACTIVIA #100 Aluminum Oxide
The INTERACTIVIA #100 aluminum oxide media emphasizes longevity and efficiency, offering a sharp angular grit that cleans and etches a variety of surfaces, including glass. It’s designed to be non-reactive so it won’t interfere with coatings during surface prep, and it’s marketed as silica-free with a claim of lasting longer than silica by up to tenfold. This makes it a strong option for projects where a durable medium is required to prep metal, glass, or stone surfaces before painting or coating.
Key features: reusable and durable; minimal risk to coatings; silica-free formulation; strong performance for metal and glass prep.
Roly Poly Glass Beads #10
Glass beads #10, with a 10 LBS package, provide a softer blasting option suitable for removing debris from aluminum, brass, plastic, and other soft metals. The eco-friendly, silica-free medium is reusable and recyclable, producing a satin finish without deep etching. Glass beads are commonly used for cleaning, deburring, descaling, and finishing, especially when a smooth surface is desired before painting or powder coating. They offer a safer alternative for parts sensitive to warping or pitting.
Key features: smooth satin finish; low risk of surface damage; eco-friendly and reusable; versatile on multiple substrates.
Buying Guide: Key Considerations for Choosing Sandblasting Media
- Application material: Harder media like aluminum oxide excel on steel and chrome, while finer grits or glass beads are better for delicate finishes on aluminum, plastics, or painted surfaces.
- Finish and texture: Coarser grits remove material quickly and roughen surfaces; finer grits produce smoother finishes suitable for coating readiness. Consider the desired texture before selecting grit.
- Media life and cost: Media longevity reduces replacement frequency but may require specific blasting conditions. Compare cycle life and compatibility with your equipment to estimate long-term costs.
- Health and safety: Silica-free options reduce health risks associated with inhalation. Eco-friendly and recycled media also support safer handling and environmental considerations.
- Wet vs dry blasting: Some media perform better in wet blasting, which can reduce dust and control clogging in confined cabinets. Check your blaster’s capability and the media’s compatibility.
- Substrate compatibility: Confirm media compatibility with your substrate (glass, stone, metal, wood) to avoid unintended etching or damage. For multi-material projects, select media with broad substrate tolerance.
- Equipment compatibility: Verify that the media grain size, hardness, and weight align with your blasting cabinet, nozzle size, and compressor capacity to prevent premature wear and clogs.
- Environmental and safety considerations: Use silica-free or recycled media where possible. Proper PPE and ventilation are essential regardless of media choice.
