**Permalloy** is a nickel-iron alloy typically made up of **about 80% nickel and 20% iron**, designed for its **high magnetic permeability**, **low coercivity**, and minimal core loss. These characteristics make it particularly suitable for applications involving alternating magnetic fields. In its foil form, Permalloy is thin, flexible, and easy to shape into components that require precise magnetic performance. It also provides good corrosion resistance and maintains stable performance across a wide range of temperatures and frequencies.
