Black Aluminum Oxide 80 mesh

Aggressive Cutting Action for Tough Jobs

Black Aluminum Oxide, also known as black fused alumina, is a virgin abrasive produced by fusing high-quality bauxite in an electric arc furnace. The resulting material is extremely hard and dense with a blocky, sharp-edged grain structure. The 80 mesh size is a medium-coarse grade that balances high cutting speed with a controlled surface profile, making it suitable for a wide range of industrial blasting applications.

Unlike softer, single-use expendable abrasives, Black Aluminum Oxide's durability allows for multiple recycling passes in contained blasting systems, significantly reducing media consumption and overall project costs. Its low iron content also prevents surface staining on non-ferrous metals and stainless steel, a critical requirement in many fabrication and maintenance projects.

Typical Applications

• Heavy Scale & Rust Removal: Ideal for stripping thick corrosion and mill scale from structural steel, bridges, and ship hulls before repainting.
• Surface Profiling for Coatings: Creates a sharp, angular anchor profile (typically 75-100 microns) essential for the strong mechanical adhesion of industrial paints, epoxies, and thermal spray coatings.
• Non-Ferrous Surface Prep: Safe for use on stainless steel and aluminum where iron contamination from steel grit must be avoided.
• Anti-Slip Surface Texturing: Used to create high-traction surfaces on industrial flooring, stair treads, and walkways.
• Stone and Glass Etching: Provides a uniform, matte finish for architectural glass, granite, and other stone surfaces.

Selection and Handling Guidance

To get the best performance from Black Aluminum Oxide 80 mesh, always ensure your blasting equipment is in good working order. Use a venturi nozzle with a bore size matched to your compressor's CFM output for optimal particle velocity. Maintain a blast pressure between 80 and 100 PSI for the most efficient balance of cleaning speed and media breakdown. In blast cabinets and rooms, a well-designed dust collection and media reclamation system is essential to remove fines and dust, allowing the sound, reusable particles to be cycled back into the blast stream multiple times.

Store your abrasive in a cool, dry area. While aluminum oxide is not hygroscopic, keeping bags sealed and off the floor prevents contamination and ensures a free-flowing media that won't clog your metering valve or blast pot.
