Brown Fused Aluminum Oxide#14 #16 #20 #24 #30 #36 #46 for blasting
Overview
Brown Fused Aluminum Oxide (BFAO) is a high-performance abrasive material widely used in surface preparation, cleaning, and profiling across industries. With exceptional hardness (Mohs 9.0) and durability, it delivers efficient material removal, consistent finishes, and extended usability—making it ideal for demanding blasting applications.
Key Features
Superior Hardness & Durability
Mohs hardness of 9.0 ensures aggressive cutting action, outperforming softer abrasives like garnet or slag.
High toughness reduces fracturing, enabling reuse in multiple cycles.
Sharp Angular Grains
Fractures to maintain sharp edges during use, ensuring consistent surface profiling (e.g., SA 2.5–SA 3 cleanliness).
Chemical Stability
Free from silica and heavy metals, complying with environmental and workplace safety standards.
Versatile Grit Range (#14–#46)
Coarse Grits (#14–#20): Rapid stripping of heavy coatings (rust, mill scale) or thick substrates.
Medium Grits (#24–#36): Balanced removal for general-purpose cleaning and weld preparation.
Fine Grits (#46): Smooth finishes or light deburring.
Low Dust & High Density
Minimizes airborne particles for cleaner operations and efficient recovery/recycling.
Typical Applications
Metal Surface Preparation: Shipbuilding, pipelines, steel structures (SSPC/NACE standards).
Coating Removal: Paint, epoxy, rust, and mill scale.
Weld Cleaning & Profiling: Prepares surfaces for welding or bonding.
Concrete & Stone Etching: Creates adhesion-promoting textures.
Aerospace & Automotive: Component refurbishment.
