Pink Fused Alumina

Pink Fused Alumina, also known as Pink Corundum, is a high-purity synthetic aluminum oxide (Al₂O₃) produced through the controlled fusion of bauxite in an electric arc furnace. Its distinctive pink color is due to the presence of chromium oxide. Pink Fused Alumina is renowned for its excellent hardness, toughness, and abrasive properties, making it suitable for a variety of industrial applications.

  • Product Category: Abrasive & Material
  • Key Features:
  • Distinctive Color: The pink color is attributed to the addition of chromium oxide, which differentiates it from other forms of alumina.
  • High Hardness: Exhibits a Mohs hardness of approximately 9.0, providing superior cutting and grinding performance.
  • Durability: Offers excellent mechanical strength and resistance to wear, ensuring long-lasting performance in abrasive applications.
  • Thermal Stability: Capable of withstanding high temperatures without significant degradation, making it suitable for high-temperature processes.
  • Chemical Resistance: Resistant to most acids and alkalis, ensuring durability in aggressive chemical environments.
Applications:

Abrasives: Used in the manufacture of high-performance grinding wheels, sandpapers, and other abrasive tools for cutting, grinding, and polishing applications. The hardness and toughness enhance the efficiency and lifespan of these tools.

Precision Grinding: Employed in precision grinding and finishing processes where a fine, consistent edge is required.

Refractories: Applied in the production of refractory materials for furnaces, kilns, and other high-temperature equipment, where the material’s durability and thermal stability are critical.
