Brown Fused Alumina Refractory

Brown Fused Alumina Refractory is made by fusing and purifying in a pouring electric arc furnace at a temperature of over 2200° C with high-quality refractory grade bauxite, carbon material, and iron filings as the primary materials. Finally, a variety of particle sizes products are made by purifying, crystallization, sorting, crushing, magnetic separation and screening, washing and acid washing, etc. The main chemical component of brown fused alumina is Al2O3, 98.65% to 99.37%. It contains slight Fe, Si, and Ti. Brown fused alumina is an excellent raw material for ceramics, precision casting, and advanced refractory materials such as the refractory aggregate, refractory brick, and filling material.

Brown Fused Alumina Refractory Characters

  • Refractory / Fireproof
    Brown Fused Alumina contains 94%-97% Aluminium Oxide(Al2O3), making it a material that resists high temperature, corrosion, and good thermal conductivity. It is an ideal raw mineral for shaped and unshaped refractory products and fireproof products, especially in steel making industry.
  • High Hardness
    Brown Fused Alumina has about 95% Aluminium Oxide(Al2O3), making it have high hardness(Mosh 9). The high hardness makes it an ideal material for cutting, polishing, grinding, sandblasting, etc., with more recycle times and not easy to break.
  • High Strength
    Brown Fused Alumina contains Al2O3 and little Titanium Oxide content (TiO2) and Iron Oxide(Fe2O3) and is a very tough material with 9 grade mosh hardness. This character makes it suitable for cutting, abrasives, polishing, and lapping various materials and can be used durably and recycled.
  • Sharp Grain
    During fusion, Brown Fused Alumina is made a crystal material with sharp edges and ideal for durable grinding, polishing, and abrasives. BFA grains are used as blasting media during the blasting industry to prepare metal, ceramic, wood, and other materials. Our Bamarc Mill can produce round shape/cubic/blocky shapes, better for abrasives and higher density.
  • High Density
    Brown Fused Alumina is a dense material with high bulk density and real gravity. It is used as a material in casting and water purifying processes.
  • Clean Material
    We wash the BFA materials by air, water, or acid and remove magnetic contents by powerful magnetic removing equipment to ensure that our materials have little dust and magnetic contents. Dust and magnetic content may cause cracks on refractory bricks or grinding wheels and may cause possible contamination to surfaces blasted or even explosion without professional care.
  • Fine Particle Distribution
    We make Brown Fused Alumina exactly according to FEPA, China GB, Japan JIS, American ANSI, or International ISO standard on Brown Fused Alumina Macro Grits and Micro Grits so that our materials are with fine particle distribution grits. And we check our sieves against standard from time to time. Our QC people check particle distribution every 2 hours during production.
