White fused alumina 1. High purity 2. high hardness 3. corrosion resistance 4. used for refractory material, abrasive tool
DESCRIPTION OF OUR WHITE FUSED ALUMINA:
With high quality alumina oxide powder as raw materials, white fused alumina is produced by fusing and extracting from crystallization.
FEATURE:
It is featured by high purity, self-sharpening, and acid-alkali and corrosion resistance, temperature tolerance. Compared with brown fused alumina, its thermal stability properties is slightly higher and toughness is slightly lower. The abrasive tools made of it are applicable for grinding high carbon copper and high-speed steel.
Advantages1. Equipped full line of test method. The laboratory is certified by government Inspection Bureau, that assures its quality stability.2. ISO9001 certified, firm management.3. Products are classified chemical washed, non-washed, shaped, non-shaped, normal bulk density and high bulk density. All products will be supplied according to customers different requirements.
