Description

3.9g/cm3 Density Calcined alumina oxide with acid and alkali resistance

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.

Performance characteristics: High temperature resistance, Corrosion resistance, Hardness,
High strength, Abrasion resistance, Good crystallization and Good cutting function.

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.
