Permalloy or Mumetal is a magnetic shielding material made of nickel-iron alloy. It has high magnetic permeability and is ideal for shielding in regions of constant or low frequency magnetic fields. As a magnetic field shielding material, it has high magnetic permeability and excellent magnetic shielding effect. The magnetic field portion can be covered with permalloy foil, or the sensor can be protected from external magnetic fields by inserting the sensor control into the permalloy housing.
Permalloy has a very high magnetic permeability and nominal coercivity, properties that make it a suitable material for shielding operations. To achieve the required shielding properties, the alloy is also subjected to high temperature annealing after the forming process to enhance the magnetic permeability and shielding properties of the material.
1J79 alloy is smelted in a vacuum induction furnace, and is made into cold-rolled strip, cold-drawn wire or hot-rolled (forged) plate and bar after hot and cold plastic deformation. In the aviation industry and other electronic industries, it is used to produce electronic components with high sensitivity, precise size, small size, low high-frequency loss, good time and temperature stability, and special functions. It is widely used in communication, instrumentation, electronic computer, telemetry, remote control, wireless charging and other systems.
Permalloy is highly permeable, magnetically shielding, easy to bend and cut, easy to bend, cut, embed, double-sided tape, weld, and handle specific situations as needed.
Permalloy foils are metal foils of high permeability materials for high sensitivity applications and high saturation magnetic flux density materials for high magnetic field applications. Products with a thickness of 10 μm are best suited for high frequency applications. But the magnetic shielding effect can also be increased by the thickness of the foil, so the thickness can be selected according to the strength of the adaptive magnetic field.
*Note: Due to the inherent properties of permalloy, direct shock during processing or transportation may result in loss of performance.
