Iron/Nickel Alloy Spooled Wire (Fe52/Ni48)

Iron/Nickel Alloy Spooled Wire (Fe52/Ni48)

Iron Nickel Alloy Spooled Wire (Fe52/Ni48) combines low thermal expansion, good magnetic stability, and mechanical durability in a continuous spooled form that ensures efficient processing. The Fe52/Ni48 composition provides dimensional control under temperature fluctuations, making it essential for precision coils, magnetic shielding, and stable electrical connections. Industries such as aerospace, electronics, and energy employ it in transformer windings, fine magnetic sensors, and structural electrical conductors. It supports advanced applications in cryogenic probes, optoelectronic devices, and specialized shielding for precision measurement instruments. Research applications include characterization of thermal expansion in drawn wires, evaluation of long-term fatigue in electromagnetic coils, and integration into hybrid composite conductors. The spooled format guarantees ease of handling, uniform diameter, and repeatable winding properties, reinforcing its role as a critical material in industrial systems and scientific experimentation requiring controlled thermal and magnetic behavior.
