White Fused Alumina

Product Description

AL2O3 have the characteristics of high hardness (second hardest mineral after diamond), sharpness, tenacity, stable chemical property, heat resisting and corrosion resisting. This sharp angular abrasive is fast cutting and does not contain free silica. It gives a mat finish, or produces anchor patterns on most metal surfaces and can be used economically in a closed system blasting machine. APPLICATIONS The range of application is limitless for blasting, lapping, polishing, etc- the removal of sand from casting or surface preparation prior to enamelling, plating or bonding: etching: descaling: deburring: cleaning moulds: glass carvings and decorative works in glass industry.
White fused alumina is made from high quality Bayer-processed alumina by fusing in an electric arc furnace at high temperature. It has high hardness and better cutting 
characteristics. It is suitable for manufacturing of vitrified 
and resinoid tools, and for lapping, polishing and blasting. 
It can be also used to make engineering ceramic and superior 
refractory products.
