Brown Fused Alumina / Brown Aluminum Oxide / Brown Corundum
Brown fused alumina is a kind of artificial corundum, with Al2O3 95%Min. HS code: 2818101000
By application it can be divided into:
Then F sand can be divided into:
Feature: Higher TiO2
The grinding wheels produced by ABV with blue color, no reticulate crack, high grinding efficiency
High toughness, good self-sharpness, super grinding capacity, the cutting discs produce by ABR is of great cutting efficiency
High bulk density, no free silica, large specific gravity, good toughness, is an ideal "environmental" type sand blasting material, widely used in aluminum parts, copper work piece, precision molds and other fields;

What Is Difference Between Tilting Furnace Melted BFA & Fixing Furnace Melted BFA ?
Ball Milling & Barmac Process?
1. Tilting furnace process affects SiO2, SiO2 <1% by Tilting furnace, SiO2 <1.5% is by fixed furnace.
2. Barmac affects the density, the grain shape is rounder & the density is greater than ball milling
3. The Tilting furnace made BFA has high Al2O3 content
4. The corundum has good toughness & more suitable for abrasive products by dumping furnace process
The difference between F-grit & P-grit Abrasive grains:
F-grit is more suitable for bonded abrasive tools.
P-grit is more suitable for coated abrasive tools. It is with a closer tolerance size distribution, lower density, and better self-sharpening ability than non-P-grit abrasives, which means that they offer a more consistent surface finish.
Grit size: 16#, 20#, 24#, 30#, 36#, 46#, 54#, 60#, 80#, 100#, 120#, 150#, 180#, 220#
Micropowder: 240#, 280#, 320#, 360#, 400#, 500#, 600#, 800#, 1000#, 1200#, 1500#, 2000#
Refractory Grit size:1-0mm, 3-1mm, 5-3mm, 5-8mm, -200mesh, -240mesh, -320mesh.
