Nickel Alloy Moly Permalloy - Properties, Applications and Technical Data
Moly Permalloy is a nickel-iron alloy with very high magnetic permeability and very good magnetic properties.
The material is used in applications where low coercivity, minimal hysteresis loss and high magnetic susceptibility are crucial.
Moly Permalloy is often used in transformers, magnetic sensors, magnetic shielding and other electronic components where stable magnetic properties are required.
Properties of Moly Permalloy
Moly Permalloy belongs to the family of soft magnetic nickel-iron alloys.
The alloy consists mainly of nickel, iron and molybdenum. The addition of molybdenum improves the magnetic stability and gives very high magnetic permeability.
Type: Soft magnetic nickel-iron alloy
Alloy: Ni-Fe-Mo
Structure: Austenitic nickel-iron alloy
Alternative names: Moly Permalloy, Permalloy, N14080, 80 Permalloy, High Permeability Permalloy, Ni-Fe-Mo alloy, 1.3910, 1.3911, Mu-Metal
Typical composition: about 80 percent Ni, 4 to 5 percent Mo, the remainder Fe
