Permalloy refers to Ni-Fe alloy. Main technical characteristics are as follows: ⋆High magnetic permeability, low loss, small magnetostrictive coefficient, etc., the inductors and other components produced by Permalloy have strong anti-saturation ability, large inductance, good stability, small size, energy saving and high efficiency. ⋆Commonly used Permalloy grades are 1J50, 1J79, 1J85, etc. ⋆Good processability, good surface quality, excellent welding performance. However, because the magnetic properties of Permalloy, especially the magnetic permeability, are sensitive to mechanical stress, the products after annealing are not suitable for collision, bending and other operations. Excessive installation stress should be avoided during application. ⋆ The main feature of low temperature Permalloy 1JL0 is that it has high magnetic properties especially the magnetic permeability at cryogenic temperatures such as below 2-77 K. The initial magnetic permeability is kept above 20,000. After special preparation and cyclic annealing, the initial magnetic permeability can reach up to more than 50,000, and is especially suitable for large-scale precision magnetic shielding components such as synchrotron radiation and free electron laser superconducting cavities used in cryogenic temperatures. ⋆Contains more nickel elements, and has good corrosion resistance in general environment, especially high-nickel Permalloy, most products do not need special anti-rust treatment such as coating.
