Fused white alumina, also known as white fused alumina or WFA, is a synthetic abrasive material made from high-purity alumina (Al2O3) oxide. It is produced by melting a mixture of alumina and other raw materials in an electric arc furnace, then cooling and crushing the resulting material into grains of various sizes.

Fused white alumina has a very high degree of purity and hardness, making it an excellent abrasive for grinding, polishing, and cutting applications. It is also highly resistant to wear and corrosion, making it suitable for use in harsh environments.

White fused alumina is commonly used in applications such as precision grinding of tools, production of high-quality refractory materials, and as a raw material for producing abrasive products such as sandpaper and grinding wheels. It is also used in the production of ceramics, catalysts, and other high-temperature materials due to its high melting point.

Fused white alumina is available in a variety of grain sizes, with larger grains typically used for grinding and polishing applications, and smaller grains used for precision cutting and grinding. It is also available in a range of purities and hardness levels to suit different applications.

Overall, fused white alumina is a high-quality, versatile material that offers excellent abrasive properties and high purity, making it a valuable material for a wide range of industrial applications.
