Description:
YFA-WFA is produced by fusing alumina block in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has predominantly large crystals of Alpha Alumina. Ingots are crushed, ground, and precision screened in our new sizing plant to obtain very consistent sized fractions. Magnetic iron from crushing is removed by rare earth magnets to ensure very low levels of iron in the finished products. Close sized fractions are available or precision blended to specification. This process ensures a very consistent sizing from coarse to fines which is critical in many applications.
Applications:
YFA-WFA is designed for general industrial use in operations such as lapping, polishing, refractory coating for investment cast shells, decorative non-skid tile, and pressure blasting. It is used where a high purity and/or highly friable abrasive is desired.
Advantages:
1.The largest WFA manufacturer in China.2.Commissary company of the National Technical Strandardization Committee of Abrasives.
3.High purity of 99% min.4.Prompt delivery: within 15 days after the receipt of the oder.5 Competitive and reasonable price.
6 Imported bauxite from Australia.
