Sand Blasting Aluminium Oxide Brown Fused Alumina

FANCHUANG Brown Fused Alumina: The Ultimate Abrasive for Industrial Excellence

FANCHUANG Brown Fused Alumina (BFA) is a premium abrasive material engineered through the high-temperature smelting of bauxite, anthracite, and iron filings in an electric arc furnace. With an Al₂O₃ content of 95%-97%, it delivers exceptional durability, high-temperature resistance, and superior grinding performance. Its minor inclusions of Fe, Si, and Ti further enhance its structural integrity, making it indispensable across heavy industries such as steel, cement, glass, and chemical processing.

Key Properties & Applications

Unmatched Hardness: Ideal for abrasive blasting, grinding wheels, and cutting tools.

Thermal Stability: Withstands extreme temperatures, perfect for refractory linings and kiln furniture.

Corrosion Resistance: Prolongs equipment lifespan in harsh chemical environments.

Versatility: Available in multiple grain sizes for precision surface treatment.

High quality abrasive grade bauxite

Fanchuang workers select high-quality grinding grade bauxite for smelting to ensure the quality from the root.The content of Al_²O₃ is up to 85%.

Secondary refining

All brown corundum is refined twice for an additional three hours after industry standard smelting time,in order to improve product quality.

Strict grading

After smelting,the brown corundum blocks are manually screened and graded by workers to ensure that each batch is a high-quality product.

Perfect technology

Our excellent technological level has created high quality brown fused aluminum oxide,with relatively low cost and remarkable product effects.We use famous and high-quality high-power magenetic separators with 5 channels to strongly remove silicon&iron impurities to ensure product quality.

Strict quality control

We have excellent talents of management,professional technical team,strict quality testing procedures.We are scrupulous about every detail,thus our professional QC  team will carry out strict quality inspection on every production process.

 

Brown corundum is called the teeth of industry,mainly used in refractory materials,grinding wheels,sandblasting,abrasive rust removal,emery cloth and other aspects.

1 The manufacture of high-grade refractory materials,castables,refractory bricks and so on

2 Sandblasting-used in aluminum material,copper material,glass,precision mold and so on

3 Grinding grade abrasives-used in picture tube,optical glass,monocrystalline silicon,lens,watch glass,crystal glass,jade and other fields

4 Resin abrasives-abrasives have suitable color,good hardness,toughness,suitable particle section type and cutting edge retention.

5 Coated abrasives-abrasives are the raw materials of sandpaper,abrasive cloth and so on.

6 Functional fillers-ued for automotive brake parts,special tires,special construction products ,etc,wear-resistant materials for the airstrip,dock,parking,industril floor,sports venues.

7 Filter medium-using granular abrasive as the bottom medium of the filter bed,purifying drinking water or wastewater;suitable for non-ferrous metal beneficiation;oil drilling mud weighting agent.

8 Hydraulic cutting-abrasive as the cutting medium,relying on high pressure hydraulic jet for basic cutting, used in the cutting of oil pipelne,steel and other parts.
