Brown Fused Alumina Grit

Brown Fused Alumina Grit Typical Particle Distribution(Sieving) and Chemical Specifications

Brown Fused Alumina Grit Characters

• Refractory/Fireproof
  Brown Fused Alumina contains 94%-97% Aluminium Oxide(Al2O3), which makes it a material that resists high temperature, corrosion, and has 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 good for cutting, abrasives, polishing, lapping various materials, and being 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. During the blasting industry, BFA grains are used as a blasting media to prepare the surface of the 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 true 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.
