Pink Fused Alumina (PFA)

Pink Fused Alumina (PFA) is a high-performance abrasive made from aluminum oxide with added chromium oxide, which gives it a distinct pink color. The chromium content enhances toughness and durability, making PFA ideal for demanding grinding and cutting tasks.

High Hardness: The incorporation of chromium oxide enhances the hardness of Pink Fused Alumina, allowing it to withstand heavy wear and extend tool life.
Enhanced Toughness: Its unique structure provides excellent toughness, minimizing the risk of fracture during intense grinding processes.
Angular Grain Shape: The sharp, angular grains contribute to efficient cutting action, enabling faster material removal and superior surface finishes.
Thermal Stability: Withstands high temperatures without degradation, making it suitable for applications that require heat resistance.

Pink Fused Alumina Materials Applications

 

Precision Grinding Tools – Perfect for high-hardness materials such as hardened steel.
Cutting & Sharpening – Ideal for tools requiring both hardness and toughness.
Surface Finishing – Delivers a smooth, even finish on metal and alloy surfaces.
Refractory Applications – Used in high-temperature environments for its excellent resistance to wear.
