Brown Fused Alumina Fine Grit is engineered for industrial applications requiring precise surface finishes. With controlled particle distribution in the F60 to F120 range, it’s ideal for polishing, blasting, and fine grinding operations across multiple industries.
Tightly controlled grit sizing from F60 to F120 for uniform blasting and polishing performance.
Rated Mohs 9.0, ideal for removing rust, burrs, or coatings while maintaining base material integrity.
Minimizes surface contamination, supporting pre-treatment and coating adhesion in downstream processes.
Used for precise deburring, descaling, and smoothing of steel and aluminum parts.
Improves paint adhesion by creating a clean and uniform substrate surface.
Fine grit levels enable polishing of stainless steel, ceramics, and non-ferrous metals.

Brown Fused Alumina Fine Grit is a dependable solution for precision surface treatments across industrial sectors. With controlled sizing, high hardness, and flexible applications, it's an ideal choice for quality-focused B2B buyers.
While white fused alumina offers higher purity, BFA fine grit is more economical and durable, making it ideal for general-purpose polishing and blasting without compromising on performance.
Compared to coarser grits, F60–F120 provides a smoother finish for delicate surfaces. It's also easier to handle and clean than ultrafine microgrits, making it a balanced choice for industrial use.
Used for precise deburring of aluminum turbine blades and structural parts.
Provides consistent surface prep before painting or powder coating body panels and chassis parts.
Effective in cleaning, polishing, and coating preparation of equipment surfaces in factories and plants.
