Permendur 2V similar with Hiperco 50A and Chinese 1J22 bar
Permendur 2V
is a soft magnetic alloy which has been used primarily as magnetic core material in electrical core material in electrical equipment requiring high permeability values at very high magnetic flux densities. The magnetic characteristics of this alloy permit weight reduction, reduction of copper turns, and insulation in the end product when compared to other magnetic alloys having lower permeabilities in the same magnetic fieldrange.
