1J50 (FeNi50) Soft Magnetic Alloy Sheet / Plate is a high-performance nickel-iron soft magnetic material containing approximately 50% nickel. It offers excellent magnetic properties, including very high magnetic permeability, low coercivity, and low hysteresis loss. After proper vacuum or hydrogen annealing, the material achieves significantly improved magnetic stability and superior soft magnetic performance.
1J50 sheet also features relatively high electrical resistivity, which helps reduce eddy current losses under alternating magnetic fields, making it suitable for medium and high-frequency electromagnetic applications. It has a uniform microstructure, stable dimensions, and good mechanical properties, ensuring reliable performance in precision components.
In addition, 1J50 exhibits good cold working and machining capabilities, allowing it to be processed by stamping, cutting, bending, and other precision fabrication methods according to different design requirements.
This material is widely used in transformer cores, relays, solenoids, electromagnetic shielding parts, sensors, and precision instruments. It is also commonly applied in aerospace, industrial automation, telecommunications, and high-end electronic systems where stable magnetic performance and high reliability are required.
Overall, 1J50 soft magnetic alloy sheet is an ideal material for applications requiring efficient magnetic conduction, low energy loss, and long-term stable electromagnetic performance.
