3-5mm Brown Fused Alumina Grade A- BFA Blasting Media for Steel Derusting & Surface Preparation
Brown fused alumina is a high-hardness synthetic abrasive produced through high-temperature smelting. It is wear-resistant, heat-resistant, and highly durable, and is primarily used in sandblasting for rust removal, wear-resistant flooring, refractory materials, grinding wheel manufacturing, and anti-slip road surfaces. It serves as a high-quality aggregate and abrasive widely used in industry.
3–5 mm Brown Fused Alumina Grade A- is produced from high-quality bauxite through high-temperature electric arc melting, followed by precise crushing and screening. It features uniform particle size and sharp edges, combining high hardness, high toughness, and heat resistance. As a preferred aggregate for “heavy-duty, wear-resistant, and high-temperature” applications in industrial engineering, it offers both cost-effectiveness and practicality, making it ideal for bulk purchasing and long-term, stable supply needs.
