Inquire Now

As a professional supplier of abrasives and technical solutions, Alfa Chemistry offers brown fused alumina (BFA) micro-powder (HG-AB020), engineered for precision, performance, and versatility. Manufactured from high-quality BFA grain sand, this micro-powder is processed through advanced techniques including wet crushing, magnetic separation, acid pickling, and precision washing or overflow classification. The result is a consistently pure, high-hardness abrasive ideal for demanding applications across industries.

Key Features

High Hardness & Strength: With a Mohs hardness of about 9.0, BFA micro-powder delivers excellent cutting, grinding, and polishing efficiency. Its robust mechanical properties ensure long-lasting performance even under intense pressure.
Outstanding Toughness: Designed to resist fracturing, this micro-powder maintains structural integrity under impact, making it suitable for both soft and hard substrates.
Thermal & Chemical Resistance: Excellent resistance to high temperatures, oxidation, and chemical corrosion allows the powder to perform reliably in harsh environments.
Superior Surface Finish: Ideal for applications requiring high precision and smooth finishes, such as polishing pastes, waxes, and abrasives.
Color & Appearance: Typically light brown in color; finer grades may appear greyish-white due to particle size effects.
