Density and specific heat capacity of precision alloys table
General Characteristics
Alloy 50H consists of nickel (49-50.5%) and iron alloyed with chromium, copper, cobalt. The alloy refers to permalloys, characterized by magnetoresistance effect, good magnetic permeability in weak fields, small coercive force, magnetostriction close to zero. The latter quality determines the field of application of this alloy in high-precision mechanical devices, industrial sensors working in alternating magnetic field.

Comparative electromagnetic properties
The saturation induction values of low-nickel permalloys are one and a half times higher compared to high-nickel alloys, and the magnetic permeability is lower than that of high-nickel alloys. Low-nickel alloys are characterized by lower resistivity and are less suitable for use at high frequencies. Low nickel permalloys undergo critical cooling to achieve better performance. Their magnetic permeability decreases with increasing frequency, and the rate of decrease affects its original value. This effect is caused by eddy currents in the material due to its low resistivity.
Using
Production of transformer plates and parts of recording magnetic heads, for distributed capacitance compensators that reduce distortion of telecommunications signals. Today, some magnetic field sensors, such as the HMC1002 biaxial magnetometer chips use the magnetoresistive properties of permalloy. Flat-rolled steel is in demand as a shield from magnetic field - for example, MRI radiation, as an element of electron microscopes and other ultra-sensitive devices. It is used in production of protective covers for microcircuits and magnetically oversensitive coils.
