1j79 Permalloy Strip E11c Strip Soft Magnetic Alloy ribbon for Magnetically Shielded
Classification: precision soft magnetic alloy
Supplement: Alloy with high permeability in weak fields at saturation
induction 0.65-0.75 T. Alloy 1J79/ permally high squareness of the
hysteresis loop and a low coefficient of magnetization reversal
Application: For small cores of transformers, chokes and relays operating in
weak fields, magnetic shields. In the small thickness (0.05 ± 0.02
mm) - cores for pulse transformers, magnetic amplifiers and solid
state relays
