Brown Fused Alumina(BFA),also calleded Brown Fused Aluminium Oxide,Brown Aluminum Oxide or Brown Corundum,named by its mainly brown color, is an artificial electro fused corundum obtained from reduced fusion of high quality bauxite together with other raw materials in 2000ºC electric arc furnaces. Bauxite used for producing of BFA contains high Aluminium Oxide(Al2O3). After the fusion process, the materials are mixed and fused into liquid materials, then cooled down and crushed(milled)into lump sizes. The lump sizes are then crushed into finer grades or powders and refined by sieving equipment into materials of different particle distribution for different applications. We also select quality Brown Fused Alumina for further processing like Heat Treatment, Micro Grits Fine Grade Manufacturing(Sieve by Water). Brown Fused Alumina is an important material for abrasives,refractory and blasting industries used for different applications. It's a hard,tough,abrasion-resistant,heat-resistant,dense material. We make according to FEPA,JIS,GB,ISO standard to customers in different industries and countries. 0-1mm,1-3,3-5mm etc for refractories, FEPA F sizes for bonded abrasives aluminium oxide tools, FEPA P sizes for coated abrasives aluminium oxide products. It's an important industrial abrasives,refractory minerals and sandblasting media. The Brown Fused Alumina we make are with fine sieve distribution, good chemical contents and bulk density for high quality abrasives and refractory applications, also a nice media for sandblasting,shot blasting, polishing,painting etc. Similar materials we make are White Fused Alumina .

BFA Characters

Refractory/Fireproof

Brown Fused Alumina contains 94%-97% Aluminium Oxide(Al2O3) which makes it an material which 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) which makes it have high hardness(Mosh 9). High hardness makes it an ideal material for cutting,polishing,grinding,sand blasting etc with more recycle times and not easy to break.

High Strength

Brown Fused Alumina contains Al2O3 and little content of Titanium Oxide(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 of 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.During blasting industry, BFA grains are used as a blasting media to prepare surface of metal,ceramic,wood and other materials. Our Bamarc Mill can produce round shape/cubic/blocky shapes,better for abrasies and with 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 make sure that our materials are with 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.
