Product Overview – White Fused Alumina
White Fused Alumina (WFA) is a high-purity synthetic abrasive made by fusing industrial-grade alumina in an electric arc furnace. Moreover, it combines exceptional hardness, sharp cutting edges, and strong chemical stability. As a result, manufacturers choose WFA for precision blasting, surface finishing, and polishing of stainless steel, aluminum, ceramics, glass, and electronic components. In fact, its iron-free composition ensures contamination-free results, making it ideal for high-end industries.
Key Features of White Fused Alumina
High Purity & Cutting Ability: WFA delivers precise micro-deburring and fine polishing.
Non-Contaminating Results: It contains no iron, so users avoid stains or surface defects.
Versatile in Wet & Dry Blasting: Furthermore, it performs reliably in both wet and dry applications.
Thermal & Chemical Stability: It resists heat and chemicals, ensuring long-term stability.
Low Friability: Consequently, grains last longer, and operators reuse them many times.
