White Fused Alumina

White Fused Alumina (WFA) is a high-purity, white-colored abrasive material made from the fusion of high-grade aluminum oxide. Produced by melting bauxite ore in an electric furnace, White Fused Alumina is known for its exceptional hardness, high purity, and consistent quality. It is widely used in abrasive, refractory, and industrial applications where a clean, high-performance material is required.

  • Product Category: Abrasive & Material
  • Key Features:
  • High Purity: Composed of nearly 99% aluminum oxide (Al₂O₃), ensuring minimal impurities and consistent performance.
  • White Color: The white coloration of the material indicates its high purity and absence of iron content, which is ideal for applications requiring clean and non-reactive abrasives.
  • Hardness: Exhibits exceptional hardness, making it effective for cutting, grinding, and polishing operations.
  • Thermal Stability: Capable of withstanding high temperatures without degradation, suitable for high-temperature processes and applications.
Applications:

Abrasives: Used in the manufacturing of grinding wheels, sandpapers, and blasting media for efficient cutting, grinding, and polishing of metals, ceramics, and other materials.

Refractories: Employed in the production of refractory bricks, linings, and castables for furnaces, kilns, and reactors, where its high-temperature resistance and durability are critical.

Ceramics: Applied in the production of advanced ceramics and ceramic composites, where its purity and hardness enhance the performance of the final product.

Industrial Coatings: Utilized as an ingredient in industrial coatings and surface treatments to improve durability and performance.
