Brown fused alumina

1. Description:

a.Through calcination, the impurities are vaporized and the surface of abrasives become more pure and rough. Meanwhile, the abrasives become more hydrophilic.

b. Medium Temperature Calcined Brown Fused Alumina/Medium Heating Brown Fused Alumina is the processing  with brown fused alumina above in high temperature heating(1000°C).

c.The crackles are engendered after calcination, increasing the toughness and hardness of abrasives.

 

2. Applications:

a.High-speed intensity sand belts

b.High-loading grinding wheels

c.Top grade bonded abrasive tools

d.Coated abrasives and sand blasting
