Description：
White fused alumina (WFA) is a high-purity synthetic abrasive produced by fusing industrial-grade alumina in an electric arc furnace. Known for its exceptional hardness, sharp cutting edges, and outstanding chemical stability, WFA is widely used for precision blasting, surface finishing, and polishing of stainless steel, aluminum parts, electronic components, glass, and ceramics. Its iron-free composition and pure white appearance ensure non-contaminating results and a clean, uniform finish, making it ideal for high-end surface treatment applications.
Key Features:
High Purity and Sharp Cutting Ability：Ensures excellent precision in micro-deburring, surface smoothing, and fine blasting tasks.
Non-Contaminating: Free of iron and other metallic impurities, preventing discoloration or staining of sensitive workpieces.
Versatile for Wet & Dry Blasting:Suitable for both wet blasting and dry polishing/lapping operations.
High Thermal & Chemical Stability: Resistant to moisture and chemical attack, maintaining performance in varied conditions.
- Low Friability: Tough grains resist breakage, allowing multiple reuses in recirculating blasting systems.
