Sheet, ribbon 50H - alloy 50
50H alloy consists of nickel (49 — 50.5%) and iron alloyed with chromium, copper, cobalt. It refers to a permalloy alloy, characterized by a magnetoresistive effect, a good magnetic permeability in weak fields, low coercive force, magnetostriction close to zero. The latter quality determines the scope of this alloy in high-precision mechanical devices, industrial sensors, operating in an alternating magnetic field.
The percentage of 10 to GOST 994−74.

Comparative electromagnetic qualities
Indicators nizkonikelevyh permalloys saturation induction and a half times higher in comparison with the RICH and permeability — less than RICH. Nizkonikelevye alloys characterized by lower resistivity, they are less suitable for use at high frequencies. In order to achieve the best technical characteristics permalloy low nickel content is subjected to critical cooling. Their permeability decreases with increasing frequency, the rate of reduction affects its original value. The reason for this effect is associated with the appearance of eddy currents in the material resulting from low resistivity.
Production of transformer plates and the parts of the recording magnetic heads for compensators distributed capacitance, reducing distortion of telecommunication signals. Today some sensors of magnetic fields such as chips in a biaxial magnetometer HMC1002 used magnetoresistive properties of permalloy. Flat steel demand as a screen of magnetic fields — for example, MRI radiation, as an element of electron microscopes and other ultra-sensitive devices. Used in the manufacture of protective covers for the chips and ultra-sensitive to the magnetic field coils.
