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.
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.
