White Fused Alumina High Hardness Long and Durable Abrasives
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.
2. WFA Application
Application:
Refractory, casting,foundry.
Bonded abrasives and Coated abrasives.
Surface treatment/finishing.
Lapping, polishing, decorative non-skid tile, and pressure blasting.
Ceramic Tiles special ceramics.
Fluidized Bed Furnaces and Skin/Dental Care.
Oil stone/polishing pad, grinding wheels etc.
Anti-friction material, anti-resisting grounds/paper/ paiting.
Used for making polishing paste/solution etc.
Physical and chemical specification
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.
