Supermalloy


Supermalloy is an alloy composed of nickel, iron, and molybdenum. It is a high permeability ferromagnetic alloy used in magnetic cores and magnetic shielding in electrical components, such as pulse transformers and ultra-sensitive magnetic amplifiers. It has a resistivity of 0.6 Ω·mm2/m, an extremely high magnetic permeability, and a low coercivity. Supermalloy is used in manufacturing components for radio engineering, telephony, and telemechanics instruments.
