Sheet and strip 79NM
Steels brand 79NM — iron-nickel alloy (containing up to 82% Ni). 79NM additionally alloyed with chromium, nickel, molybdenum. 79NM alloy characterized by high magnetic permeability and the magnetoresistive effect, a small coercive force, almost zero magnetostriction. The latter quality allows the use of 79NM alloy in precision magneto-mechanical devices, which need stability in an alternating magnetic field. The electric resistance 79NM permalloy can vary up to 5%, depending on the strength and direction of the magnetic field.
The percentage of 10 to GOST 994−74.
Magnetic field sensors, such as a biaxial magnetometer circuit HMC1002. Flat-rolled 79NM in demand as a screen of magnetic fields — for example, MRI radiation, as an element of electron microscopes and other ultra-sensitive devices. 79NM Used in the manufacture of protective covers for the chips and ultra-sensitive to the magnetic field coils.
Comparative electromagnetic qualities
Indicators saturation induction RICH 79NM permalloy and a half times less than the nizkonikelevymi and permeability — higher than nizkonikelevyh. Last characterized by low resistivity, they are less suitable for use at high frequencies. The practical significance of computer technology and automation purchased RICH permalloy similar 79NM having a rectangular hysteresis loop.
