product description:
Permalloy refers to an iron-nickel alloy with a nickel content of 30-90%. The grades of domestic permalloy are: 1J34, 1J50, 1J51, 1J67, 1J79, 1J77, 1J85; 1 means soft magnetic alloy, J means precision alloy, and the following number means nickel content. Application characteristics of permalloy: The operating frequency is from 50Hz to 20kHz, and the temperature is relatively high, such as high-precision current, voltage transformers, pulse transformers, isolation transformers, magnetic amplifiers, etc.
According to the content of nickel in the nickel-iron alloy, permalloy can be used in different occasions.
35% to 40% have lower core loss. Such alloys are suitable for square wave transformers, DC converters, etc.
45% to 50% Alloys in this composition range have the highest saturation magnetization among permalloys. Commonly used in magnetic amplifiers, choke coils and transformers.
50%～65% The alloy in this composition range has the highest Curie temperature and high saturation magnetization, which can produce strong induced magnetic anisotropy. Suitable for inductive components.
70% to 81% Permalloy in this composition range has the highest magnetic permeability. Such alloys are suitable for transformers, choke coils, magnetic heads, magnetic shields, etc.
Typical applications of permalloy in audio coupling transformers.
