Product Description Grained Abrasives F240 Calcined white Alumina Oxide granular PRODUCTION 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 characterizedby 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 ApplicationPerformance 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.
