Brown Fused Alumina is produced through high-temperature smelting of bauxite, followed by crushing, magnetic separation to remove iron, and sieving into various particle sizes. It features a dense texture, high hardness, excellent toughness, and superior refractoriness. Depending on the smelting method, it is categorized into fixed-furnace and tilting-furnace types, with the latter offering higher purity. Based on particle size distribution, it is divided into F-sand （ideal for consolidated abrasives and sandblasting） and P-sand （suited for coated abrasives）.

Brown Fused Alumina: High-Performance Abrasive & Blasting Media

Our Brown Fused Alumina is a tough, sharp, and highly recyclable abrasive. It is engineered for heavy-duty industrial applications, surface preparation, and the manufacturing of premium abrasive tools.

1. Industrial Sandblasting & Surface Preparation

Marine & Infrastructure: Heavy-duty sandblasting for ship hulls, large steel structures, and bridges to ensure superior coating adhesion.
Heavy Industry: Precision cleaning and surface conditioning of metal molds, steel molds, and industrial tooling.
Tooling & Hardware: Surface treatment for metal tools, hardware, and stainless steel tableware to achieve a uniform finish and remove oxidation.

2. High-Tech & Precision Engineering

Semiconductor Industry: Specialized sandblasting for semiconductor components and delicate electronic frames.
Medical Devices: High-precision sandblasting and grinding for surgical knives, medical sleeves, and orthopedic instruments.
Surface Engineering: Controlled roughening of metal parts to optimize surface area for bonding or thermal spraying.

3. Abrasive Tool Manufacturing

Resin-Bonded Abrasives: Primary raw material for high-strength cutting discs, grinding wheels, and heavy-duty resin-bonded tools.
Durability: High toughness ensures the grain resists fracturing, providing a long service life in high-speed applications.

4. Consumer Goods & Decorative Finishing

Craftsmanship: Aesthetic sandblasting for buttons, metal handicrafts, and fashion accessories.
Natural Materials: Specialized surface treatment for wooden and bamboo products to create unique textures or prepare for finishing.

5. Construction & Wear Resistance

Industrial Flooring: Used as a premium wear-resistant aggregate for heavy-duty floor systems, providing extreme hardness and anti-slip properties.
Reinforcement: Ideal for areas subject to high mechanical impact and constant friction.

Why Choose Our Abrasive Grade BFA?

High Recyclability: Its exceptional toughness allows it to be reused multiple times in blasting rooms, significantly reducing operational costs.

Aggressive Cutting: Sharp, blocky grains provide fast material removal rates across all metal types.

Contamination-Free: Low iron content prevents “rust spotting” on stainless steel and non-ferrous surfaces.
