Description
Manufacturer White Fused Alumina/ White Corundum/ White Aluminium OxidePRODUCTION DETAILS
1. White Fused Alumina/WFA/corundumWhite 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 ApplicationApplication:
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. Specification
