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.

Wear resistant alloy high permeability
Wear resistant high permeability alloys not only has high initial
permeability, low coercive force, high resistance, and high
hardness, magnetism is not sensitive to stress, alloy has good wear
resistance.Generally applicable to the production of tape recorder,
video, disk, digital tape machine and some movie projector head
core material, usually referred to as the head of alloy.In addition
can also be used in micro motors, transformers, sensors, magnetic
amplifier and the core of high frequency inductive components.
