Industrial Abrasives Brown Fused Alumina Oxide BFA 95% Fireproof

Brown Fused Aluminum Oxide BFA 95% for Bonded & Industrial Abrasives
 
Brown Fused Alumina 95% Introduction

Brown fused alumina is an Aluminium oxide, produced by fusion of calcined bauxite in Electric Arc Furnaces at a temperature of abt. 2000 degree Celsius. BFA has a high refractoriness, is extremely hard and stable. According to the application and requirements BFA is produced in Higgins kiln or in tilt kilns. We can deliver BFA grades with different chemical purity in different standard refractory and abrasive grain sizes.

 
Brown Fused Alumina Characteristics
 
Refractory / Fireproof
 
Brown Fused Alumina contains 94%-97% Aluminum 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 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 Barmac Mill can produce round shape/cubic/blocky shapes, better for abrasives 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.
