medium permeability of medium magnetic saturation soft magnetic alloy
This kind of alloy of nickel content in 45% ~ 50%.The saturated magnetic induction intensity from 1 to 1.5 T, higher
than that of high permeability alloy under high magnetic saturation
alloy, its permeability and coercive force between the two types of
alloys.Mainly used for the secondary magnetic field work of all kinds of
transformers, relays, electromagnetic clutch, iron core, the
resistivity of this kind of alloy of high magnetic full alloy than
the high resistivity, and thus can be applied to high frequency.

Soft magnetic alloy are in weak magnetic field with high
permeability and low coercive force of alloys.This kind of alloy
are widely used in radio electronics, precision instruments and
meters, remote control and automatic control system, the
combination is mainly used for energy conversion and information
processing, the two aspects of is an important material in the
national economy.
