White Fused Alumina oxide#220 for Wearing Compound
Introduction
White Fused Alumina Oxide (WFA) #220 is a high-purity, synthetic abrasive grain widely used in wearing compounds for surface preparation, polishing, and grinding applications. With its exceptional hardness (9.0 on the Mohs scale), sharp edges, and thermal stability, it delivers superior performance in abrasive blasting, grinding wheels, and bonded abrasives. The #220 mesh size ensures a fine yet aggressive cutting action, making it ideal for precision finishing and wear-resistant coatings.
Key Features
-
High Purity & Consistency – Produced from premium-grade alumina, WFA #220 contains over 99% Al₂O₃, ensuring minimal impurities and consistent performance.
-
Optimal Grain Size – The #220 mesh (53–63 microns) provides a balanced blend of cutting efficiency and smooth surface finishes.
-
Exceptional Hardness & Durability – Its tough crystalline structure resists fracturing, extending abrasive life in high-stress applications.
-
Chemical Inertness – Resistant to acids and alkalis, making it suitable for harsh environments.
-
Thermal Stability – Withstands high temperatures without degrading, ideal for heavy-duty grinding and sandblasting.
Applications
-
Wearing Compounds – Enhances durability in anti-slip coatings, floor treatments, and wear-resistant linings.
-
Surface Preparation – Used for precision grinding, deburring, and polishing metals, ceramics, and composites.
-
Abrasive Blasting – Effective for cleaning and etching surfaces without embedding contaminants.
-
Bonded & Coated Abrasives – Incorporated into sandpapers, grinding wheels, and honing stones.
Advantages Over Alternatives
Compared to brown fused alumina or silicon carbide, WFA #220 offers:
-
Whiter finish (no iron oxide traces).
-
Lower friability, reducing dust generation.
-
Eco-friendly – Free from silica and heavy metals.
Conclusion
White Fused Alumina Oxide #220 is a versatile, high-performance abrasive for demanding wearing compounds.
