FeNi Alloy 1j85 1j87/1j92/1j93/1j94/1j95 / 1j80 High Permeability Soft Magnetic Alloy Permalloy 80 Wire
General Description
Soft magnetic alloy outer magnetic field under the action of easy magnetization, basic disappear after removal of magnetic field of magnetic induction intensity and magnetic alloys.
The hysteresis loop area is small and narrow, coercive force generally below 800 a/m, high resistivity, eddy current loss is small, high permeability, high saturation magnetic induction.Are generally processed into sheets and strip.Melt was prepared.Mainly used for electrical appliances, telecommunications industry in various core components (such as transformer core, relay iron core, choke coil, etc.).Commonly used soft magnetic alloy has a low carbon electrical steel, eminem iron, silicon steel sheet, soft magnetic alloy, iron, cobalt soft magnetic alloy, nickel iron iron silicon soft magnetic alloy, etc.
The magnetic properties of soft magnetic alloy mainly is: (1) coercive force (Hc) and low hysteresis losses (Wh);(2) resistivity (rho) is higher, low eddy current loss (We);(3) initial permeability (mu 0) and the maximum high
The main kinds of
Can be divided into low carbon electrical steel and eminem iron, silicon steel sheet, nickel iron soft magnetic alloy, iron, cobalt soft magnetic alloy, iron, silicon aluminum soft magnetic alloy, etc., in terms of electric power industry, mainly used in high magnetic field with high magnetic induction and low core loss of the alloy.In the electronic industry, mainly used in low or medium under magnetic field with high permeability and low coercivity of the alloy.Under high frequency must adopt the thin strip or higher resistivity of the alloy.Commonly used sheet or strip.
Mu 85 is a soft magnetic nickel-iron alloy with about 80 % nickel, 4.8 - 5.2 % molybdenum, a saturation induction of approx. 0.7 T, the highest technically obtainable permeability, and a very low coercive force.
Typical applications are toroidal tape-wound cores, laminations, shieldings, electromagnetic relays.
