Iron/Nickel Alloy Spooled Wire (Fe50/Ni50)

Iron Nickel Alloy Spooled Wire (Fe50/Ni50) provides excellent magnetic permeability, low coercivity, and dimensional stability in a continuous spooled format that facilitates precise unwinding for automated fabrication. The equiatomic balance enhances both mechanical resilience and soft magnetic performance, making it highly suitable for use in electronics, sensor technology, and advanced power systems. Industries employ this wire in precision inductors, electromagnetic coils, and shielding components for sensitive circuits. Specific technologies include high-frequency transformer windings, sensor probes requiring stability under thermal cycling, and fine interconnects in microelectronic systems. Research employs this alloy in studies of soft magnetic performance, fabrication of custom coil geometries, and analysis of FeNi phase distributions in drawn wire. The spooled form ensures easy integration into automated systems, repeatable processing, and consistent electrical performance, establishing it as a core material in advanced electromagnetic and structural research applications.
