Permalloys are characterized as iron-nickel alloys that have a relatively high permeability in weak fields. Belonging of every alloy to a defined group depends on extrusion rate of magnetic, electrical properties and a quantity of nickel. Marking of an actual alloy denotes a presence of nickel (79%) in a basis. Mill products from this steel relate to a category of stainless products.

It is used for details of high-accurate units with stable characteristics in a variable magnetic field. Such details possess small changes of real resistance (not more than 5%). These changes are determined with a force and fields direction. Sheet, strip are utilized for making cores of small transformers, contactless relays, pulsing transformers, magnetic intensifiers, screens. Permalloys with a high content of nickel that provide a rectangular hysteresis loop, have got a practical significance in some types of computing tools and automation devices.
