Product Description

Finish F12 - F220 Brown Fused Alumina / Aluminum Oxide For Deburring

Brown Fused Alumina Artificial Corundum

Brown Aluminium Oxide belongs to the group of electric-corundum,it is also named as brown

fused alumina. It selects the high grade bauxite, coke, iron scrap as the raw materials,

melting in an electric arc furnace,finally crushed and screened into different grains

according to different Production standards such as China GB/T, FEPA etc.

Main Products Features:
 

High Hardness,High Toughness

Brown aluminum oxide contains at least 95% alpha alumina,with Mohs hardness 9,it is an hard and tough

material.

Quick Cutting Action

Its sharp particle shape and unique crystal structure makes it good self-sharpness,it will easily break down in

the blasting process and offers new edges and quick cutting action;

Durable and recyclable

Brown aluminium oxide is able to be reused for several times,it is an durable and recyclable material.

 

Application of Brown Aluminium Oxide to make Coated Abrasives

Remove the burrs of plastics, zinc & Aluminum die castings, electronic parts, magnetic cores, bikelite etc.

as well as engraving monument markers.

 

In addition,Brown Aluminium Oxide is also used in the following applications:

Bonded Abrasives : Resin cutting discs, Ceramic grinding wheels;

Coated Abrasives: Jumbo rolls, Sand belts, Flap wheels etc.

Refractories: High alumina brick, refractory aluminium oxide lining mixture, pouring materials etc.

Anti-slip materials
