Permalloy foil is widely used in a variety of high-performance applications due to its excellent magnetic properties. It is commonly used in the manufacture of transformers, inductors, sensors, etc., where high magnetic permeability and low coercion are required, in addition if used in magnetic shielding to create electrical devices it is weakly protected from external magnetic fields. Permalloy foil is also found in precision electrical components, such as magnetic heads in data storage devices, as well as current sensors, flow gates, and other specialized magnetic applications in the electronics, aerospace and industrial industries.
