PRODUCTION  DETAILS                                                                                           

1.  White Fused Alumina/WFA/corundum


White fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. 
It has higher hardness and lower toughness comparing with brown fused alumina. It is also characterized
by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency.
 

Performance characteristics
: High temperature resistance, Corrosion resistance, Hardness,
High strength, Abrasion resistance, Good crystallization and Good cutting function.

2. WFA Application


Performance Characteristics:  High temperature resistance, Corrosion resistance, Hardness,
High strength, Abrasion resistance, Good crystallization and Good cutting function.

Applications:  Abrasives, grinding quenched alloy steel, high speed steel ,
also used for ceramics, sandblasting, polishing, grinding wheels and sandpaper.
