Nickel/Iron Alloy Rod (Ni52/Fe48)

Nickel-Iron Alloy Rod (Ni52/Fe48) delivers high magnetic permeability, excellent dimensional stability, and good machinability for precision-engineered magnetic components. The Ni52/Fe48 composition maintains consistent magnetic performance under thermal cycling, making it ideal for use in transformer cores, magnetic shielding structures, and aerospace instrumentation. Industries employ these rods in fabricating magnetic actuators, low-hysteresis cores, and precision electromagnetic devices. Specific applications include manufacturing magnetic lens components for electron microscopes, developing shielding assemblies for cryogenic systems, and producing robust magnetic couplings. In research, Ni52/Fe48 rods are used for experimental magnetic circuit designs, characterization of bulk magnetic materials, and testing of domain wall behavior under stress. Their balance of machinability and magnetic performance ensures widespread use in both industrial production and advanced laboratory investigations.
