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:

Material	Susceptibility(X_m)	Permeability(µ) x10^-6	Magnetic field
Mu-metal	20000[1]	25000 N/A²	at 0.002T
Permalloy	8000[1]	10000 N/A²	at 0.002T
Transformer iron with ρ=0.01µΩ·m	4000[1]	5000 N/A²	at 0.002T
Steel	700[1]	875 N/A²	at 0.002T
Nickel	100[1]	125 N/A²	at 0.002T
Platinum	2.65 x 10^-4	1.2569701 N/A²
Aluminum	2.22 x 10^-5[2]	1.2566650 N/A²
Hydrogen	8 x 10^-9 or 2.2 x 10^-9[2]	1.2566371 N/A²
Copper	-6.4 x 10^-6 or -9.2 x 10^-6[2]	1.2566290 N/A²

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.

Honger Technology Limited is a high-tech company specializing in the development and distribution of permalloy cores, amorphous microlite alloy and Mn-Zn soft ferrite cores, as well as other related magnetic products.

Our products are widely used in miniaturization and energy saving devices, electronics and power supplies. They are the environmental materials preferred by electric power plants and electronic factories.
