High Saturation magnetic induction soft magnetic alloys 1J22

Note:

Hiperco 50A alloy is a soft magnetic alloy which has been used primarily as magnetic core material in electrical core material in electrical equiment requiring high permeability values at very high magnetic flux densities.The magnetic characteristics of this alloy permit weight reduction of copper turns,and insulation in the end product when compared to other magnetic alloys having low permeabilities in the same magnetic field range .
