Introduction:
Permalloy is a very widely used soft magnetic alloy. Through appropriate technology, magnetic properties can be effectively controlled, such as initial permeability exceeding 105, maximum permeability exceeding 106, coercivity as low as 2‰ Oersted, rectangular coefficient close to 1 or close to 0, Permalloy with a face-centered cubic crystal structure has good plasticity and can be processed into 1μm ultra-thin ribbons and various forms of use.

Application:current transformer
Commonly used alloys are 1J50, 1J79, 1J85 and so on. The saturation magnetic induction of 1J50 is slightly lower than that of silicon steel, but its magnetic permeability is dozens of times higher than that of silicon steel, and its iron loss is also 2 to 3 times lower than that of silicon steel. It is made into a transformer with a higher frequency (400~8000Hz), and the no-load current is small. It is suitable for making a small high-frequency transformer below 100W. 1J79 has good comprehensive performance and is suitable for high frequency and low voltage transformers, leakage protection switch cores, common mode inductance cores and current transformer cores. The initial permeability of 1J85 can reach more than 100,000 105, which is suitable for low-frequency or high-frequency input and output transformers, common mode inductors and high-precision current transformers with weak signals.
Hemei electronics current induction products have been successfully applied in electric power high-voltage transmission lines, medium-voltage distribution networks, high-speed railways, underground mines, metallurgy, dock shore power, large-scale pumps and other industries, and has accumulated a wealth of experience in the industry application engineering.
