Hiperco® 50 Foil

Hiperco® 50 Foil, composed primarily of cobalt and iron, is prized for its extremely high saturation magnetization, low coercivity, and excellent thermal stability. In foil form, it provides a thin, flexible, and efficient medium for magnetic flux control in compact electrical systems. Industries such as aerospace, defense, and power electronics employ Hiperco® 50 foil in transformers, high-frequency inductors, and laminated cores where minimizing core losses is crucial. Specific applications include precision components in more-electric aircraft systems, magnetic cores in micro-electromechanical systems (MEMS), and thin laminations in motors that demand high performance under elevated temperatures. Research shows that high-temperature aging influences its electrical resistivity, power losses, and coercivity, requiring careful thermal management during application. Studies on electrodeposited Ni-Fe foils provide insights into microstructure evolution and annealing effects, relevant for optimizing Hiperco® foil performance. In both research and industrial contexts, Hiperco® 50 Foil is highly valued for enabling energy-efficient, compact, and high-reliability electromagnetic systems.
