Premium Grade White Fused Alumina WFA for Industrial Applications
White Fused Alumina is a top-quality abrasive material that is produced using bayer alumina in an electric arc furnace at high temperatures. This material is known for its exceptional hardness and lower toughness, making it an ideal choice for grinding high carbon steel, high speed steel, and chilled steel.
In addition to its abrasive properties, White Fused Alumina can also be used as a polishing material for various applications. Its precision founding sand makes it a suitable choice for casting intricate shapes with high accuracy. The material can also be used as a spraying and coating material, catalyst carrier, and for creating special ceramics and super refractory materials.
What sets White Fused Alumina apart from other abrasive materials is its outstanding durability and resistance to wear and tear. This makes it an excellent choice for high-intensity grinding applications that require consistent performance over time. The material is also highly resistant to chemicals and can withstand exposure to acids and alkalis, making it suitable for use in harsh environments.
