Abrasives Grit F80- F180 White Fused Alumina manufacturer and supplier
PRODUCTION DETAILS
1. White Fused Alumina/WFA/corundum
Performance characteristics:
High temperature resistance, Corrosion resistance, Hardness, High strength, Abrasion resistance
Good crystallization, Good cutting function.
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.
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.
3. WFA Parameters
White fused alumina appears white particles or powder generally, True density 3.5g/cm3,
Using temperature 1850ºC, Melting point 2050ºC, Linear expansion coeffecient (1600ºC) 7-9.
It is also characterized by its high purity, acid and alkali resistance, good thermal stability.
4. Production Technical Process
Alumina powder as raw material → electric smelting → crushing → Iron removal by magnetic→ screening
→ inspection of physical and chemical → product packing → warehousing
5. Package & Shipment
6. Company Profile & Certificate
