50NP (permalloy)

With high magnetic permeability and increased saturation induction.

It is used for the production of small-sized power transformers, inductors, relays and parts of magnetic circuits operating at increased induction without magnetization or with a small magnetization. It has increased magnetic permeability and increased induction of technical saturation.
