A White Fused Alumina is fused form of calcined alumina where it’s fused in the arc furnace with controlled temperature. WFA is synthetic high purity artificial corundum used in various industries like Refractory, Foundry, Abrasive, Blasting Media, Automobile, Mechanical and much more.
WFA Grade A : WFA- A (White Fused Alumina Grade A) is high purity abrasive grade, where its used in Bonded Abrasives, Dental Application, Cosmetics, Defense Units, Machinery Industries, Polishing Industries and general industrial applications like abrasion, anti-skid, & lapping. Our WFA contains high alumina, low iron & 100% TiO2 free, which helps the material to sustain its hardness, toughness & work performance.
