    Permalloy has very high magnetic permeability compared to other materials.

    Permeability is the degree of magnetization of a material that responds linearly to an applied magnetic field. Permalloy can divert magnetic flux and effectively protect sensitive components from near by magnetic source.

    Below chart compares permeability of selected materials for reference:

    An electromagnetic wave can be divided into electric field and magnetic field.

    Magnetic field is reportedly more harmful to the human body than an electric field. Electric field (RF) can be effectively shielded by conductive material properly grounded, but the magnetic field is not easily shield and requires highly permeable material such as Permalloy or Mu-metal.

    By heat treating the steel plate (containing nickel) at high temperature, these metals’ magnetic shielding performance reaches about 96%, while high performance comes with high price. Our Permalloy, made with a newer technique, is available at reasonable prices.

    Our Permalloy is extremely thin nickel alloy and is made with special high temperature to produce superior shielding capability against a magnetic field. It is easily made into many forms and shapes by die-press, soldering and cutting.
