Permalloy usually has a face-centered cubic near the nickel concentration of 80% is about 0.
355 nm lattice constant of crystal structure.
Permalloy disadvantage is that its ductility and machinability is not high, permalloy core so need to the shape of the application (
Such as magnetic shielding)
By other high magnetic conductivity alloy (
Such as micro metal)
Made of.
Permalloy used for transformer lamination and magnetic recording head.
In addition to high permeability, the other can also include low coercive force, magnetic near-zero magnetostriction and markedly anisotropic magnetoresistance.
Low magnetostriction is important for industrial applications, so it can be used for film, variable in the membrane stress can lead to magnetic can be destructive.
Permalloy resistivity change 5%, depending on the intensity and the direction of the applied magnetic field.
