Polyimide-Insulated Nickel/Iron Alloy Wire (Ni70/Fe30)

Polyimide-Insulated Nickel/Iron Alloy Wire (Ni70/Fe30) combines the magnetic properties and mechanical strength of nickel-iron alloy with the high-temperature and chemical resistance of polyimide insulation. Its high magnetic permeability and stable resistivity make it valuable for transformer windings, magnetic shielding, and inductive sensor coils in challenging environments. Industries such as aerospace, defense, and instrumentation use it in precision magnetic devices, navigation sensors, and electromagnetic shielding systems. In research, it aids in studying magnetic stability under thermal stress, coil performance in high-vacuum environments, and long-term insulation endurance. The insulated wire’s combined electromagnetic performance and protective insulation make it essential for advanced engineering and experimental applications.
