Soft magnetic alloys 1J50 / FeNi 50 / Ni 50
Mainly used in two areas for energy conversion and information
processing
In the power industry, mainly in the high magnetic field has a high
magnetic induction and low core loss of the alloy. In the
electronics industry, mainly at low or medium alloy having a high
magnetic permeability and low coercive force. At high frequencies
shall be made on a thin strip or alloy higher resistivity. Usually
with sheet or strip.
Soft magnetic materials in exchange for use, due to the alternating
magnetic eddy currents are induced inside the material, resulting
in the loss, the smaller the resistance of the alloy, the greater
the thickness, the higher the frequency of the alternating magnetic
field, eddy current losses greater, magnetic reduce more. For this,
the material must be made thinner sheet (tape), and the surface
coated with an insulating layer, or the use of certain methods to
the surface to form an oxide insulating layer, such alloys commonly
used magnesium oxide electrophoresis coating.
Iron-nickel alloy mostly in the alternating magnetic field use,
mainly for yoke iron, relay, Small Power Transformers and
Magnetically shielded.
