Permalloy Foil is mainly made up of about 78–80% nickel and 20–22% iron, along with trace elements that boost its magnetic performance. This unique blend results in exceptionally high magnetic permeability, low coercivity, and minimal hysteresis loss. On the mechanical side, the foil showcases good ductility, flexibility, and formability, allowing it to be rolled into very thin gauges without any cracking. It maintains its shape under various operating conditions and offers moderate tensile strength, making it suitable for precision components. The combination of excellent magnetic sensitivity and dependable mechanical properties makes Permalloy Foil perfect for delicate electromagnetic applications.
