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 .
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.
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.
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.
Brown Fused Alumina is a dense material with high bulk density and
true gravity. It is used as a material in casting and water
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.
