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.
