Product Description

High Hardness Aluminium Oxide Blasting Media Brown Artifical Corundum F12-F220

1. Product Description of Brown Aluminium Oxide Blasting Media

Brown aluminium oxide is called as “the teeth of industry”,which is one kind of artificial corundum

made from bauxite, coke, and scrap iron,then melting in electric furnace under high temperature

,finally crushed and screened into different grit size, its color is brown,then it is named as brown

aluminium oxide.

3. Main Products Features:

High hardness and toughness

Brown aluminium oxide contains more than 95% Al2O3,and its special crystal form make it an hard

and tough material,which is able to remove the oxide sale or oil stain quickly from the treatment surface;


Good Self-sharpness and recyclable

Its block and sharp grit shape offers strong force,there will be new sharp edge appeared in the blasting

process,then it is an recyclable blasting media.


Consistent Particle Size

Its consistent particle size offers uniform and surface finish in blasting process.

Brown Fused Alumina is widely used in refractory industry, such as refractory brick,castables,furnace

lining,precision casting etc.


4. Main Application of Brown Aluminium Oxide in Sandblasting


Surface cleaning of work pieces,such as removing the oxide scale and oil stain after heat treatment,

raw edges of plastic molded parts etc;


Pretreatment before surface coating such as painting, baking, spraying, metal spraying, galvanizing

to increase the surface adhesion;


Surface finishing such as Polishing the metal exterior surfaces and wood products surfaces etc.


Surface sandbalsting to improve the lubrication of the mechanical surface and reduce the motion noise.
