5-50μm Permalloy foil

Permalloy refers to iron-nickel alloys with a wide range of nickel content, between 35% and 90%. The most important characteristic of Permalloy is its high permeability to weak magnetic fields. Their saturation magnetic induction is generally between 0.6 - 1.0 T.

Permalloy refers to iron-nickel alloys with a wide range of nickel content, between 35% and 90%. The most important characteristic of Permalloy alloys is their high permeability to weak magnetic fields. Their saturation magnetic induction strength is generally between 0.6 - 1.0T. 【Permalloy foil】 Performance characteristics Permalloy, an iron-nickel soft magnetic alloy with very high magnetic permeability in weak magnetic fields. To increase resistivity and improve process performance, Mo, Cr, Cu and other elements are often added to Fe-Ni binary alloys. In addition to Fe-Ni series alloys, there are also iron-silicon aluminum alloys and amorphous cobalt-based alloys that belong to Permalloy. The soft magnetic properties of Permalloy are excellent, the starting permeability μi is 37.5~125mH/m, the maximum permeability μm can reach 125~375mH/m, the coercivity Hc is 0.8A/m, and the resistivity ρ is 60~85μΩ-cm. 【Permalloy foil】Use Used for making audio transformers, mutual inductors, magnetic amplifiers, magnetic modulators, chokes, audio magnetic heads, etc.
