Brown Fused Alumina
Description:
Aluminum Oxide is manufactured in an electric arc furnace that produces an extremely tough, long-lasting grain which is graded to exacting standards. The various macrogrit sizes may be used for all types of bonded abrasive and general industrial applications.
----------------------------------------------------------------------------------------------------------------------------
Main Applications:
1) Abrasives:
bonded abrasives : resin boned abrasives cut off wheel ,ceramic grind wheel, Grinding stone, grinding wheel ,Grinding block polish wax
coated abrasives : sand paper, sand belt ,sand cloth ,sander disc flap disc ,
2) Refractory material: Mainly used for abrasion and high temperature resistance,in oxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnace etc.
3) Sandblasting abrasive: It is mainly used for various material work pieces to decontaminate,prevent corrosion,remove oxide skin,light-decorate,process pattern effect and so on.
4) Abrasion resistance ground : It is mainly used for nonslip of airport and road,chemical factory board paving and surface decorated material of dam.
5) Precision casting: casting technics of stainless steel and aluminum casting in coating.
