1. Introduction:
1J79 is a common iron-nickel-based soft magnetic alloy (Permalloy) with high magnetic permeability. It achieves sufficient magnetic permeability and magnetic saturation induction through a reasonable combination of nickel and iron. 1J79 also adds molybdenum, copper and other elements to increase the resistivity of the material to reduce the eddy current loss after it is made into an iron core. At the same time, the added elements can also improve the hardness of the material, which is especially beneficial for applications with wear such as magnetic heads.
The production process of 1J79 alloy is relatively complicated. For example, the process of sheet rolling, annealing temperature, time, and cooling speed after annealing have a great influence on the final magnetic properties of the material. At present, the products provided by Shanghai Rongkun Metal have mature production processes. The 1J79 products produced are often used in the iron core of medium and high frequency transformers or in devices that have strict requirements on sensitivity, and our company can provide deep processing services for customers. Components that have been processed and have undergone corresponding heat treatment ensure that the magnetic properties of the product can meet the requirements of relevant standards.
1J79 alloy material has the characteristics of small magnetostriction coefficient, easy magnetic permeability, fast demagnetization, small coercive force, low eddy loss, etc. It covers the entire frequency range of power frequency, intermediate frequency to high frequency. Barbed, cold-drawn bars, forgings, round steel and other forms of delivery, mainly used for switching power transformers, precision transformers, leakage switch transformers, magnetic shielding, magnetic yokes and high-sensitivity small power transformer zero sequence applications in weak magnetic fields Power transformer, low power magnetic amplifier, high frequency power supply.
