1j50 Soft Magnetic Alloy Wire Hy-Ra49

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.
