White Fused Alumina Refractory Raw Material (WFA)

YUFENGREC® White Fused Alumina are made of high quality alumina powder as raw material, by refining and crystallizing in electric arc furnace under high temperature reached 2000ºC . It has white color, slightly harder and lower toughness comparing with brown fused alumina. Its micro hardness is 2200-2300kg/mm². With high purity, better self-sharpening and grinding ability, good acid and caustic corrosion resistance, high temperature resistance and good thermal stability.

YUFENGREC® White Fused Alumina(WFA) are made of high quality alumina powder as raw material, by refining and crystallizing in electric arc furnace under  high temperature reached 2000ºC . It has white color, slightly harder and lower toughness comparing with brown fused alumina. Its micro hardness is 2200-2300kg/mm². 

With high purity, better self-sharpening and grinding ability, good acid and caustic corrosion resistance, high temperature resistance and good thermal stability.

The WFA is the main raw material for the production of unshaped and shaped refractory materials. 

For the unshaped refracdtory material , it is wide used to ladle castables, iron runner materials, refractory gunning mix materials and other high quality  monolithic refractory products;

For the dense refractory brick  , it is mainly used in the high-quality corundum brick, corundum mullite, refining steel porous plug brick, integral spray gun, steelmaking and continuous casting industry. 
It also can be used as materials for polishing, precision casting, spraying and coating,  special ceramics and high-grade refractory materials,etc.


Key Features
 
Refractory grade

* Higher hardness and high refractories over 1750℃
* High purity ,Acid and alkali resistance
* Good thermal stability


Abrasive grade
*  It does not affect the color of the workpiece
 It can be used for sandblasting in the process of prohibiting iron powder residue
* The micro powder grade is very suitable for wet blasting and grinding and polishing operations
*  It is in fast processing speed
The amount of iron oxide contained is extremely low, suitable for sandblasting operations where iron residue is strictly prohibited


Key Applications 
Corundum brick, corundum mullite, refining steel porous plug brick, integral spray gun, steelmaking and continuous casting industry.
