High-Purity Electrolytic-Iron Flakes in Aerospace: Meeting Extreme Demands
In the aerospace industry, where material failure is not an option, XTiron's 99.99% electrolytic-iron flakes set the benchmark for reliability. Engineered through a proprietary 8-stage electrowinning process, our material delivers the ultra-low impurity levels (<100 ppm total contaminants) required for spacecraft, jet engines, and defense systems.
