MAGNETIC SHIELDING ALLOYS

Alloy materials are used as magnetic shields in many technological devices we use in daily life. Magnetic fields entering the alloy consisting of metals with high magnetization properties travel through the material and circulate around the area to be protected. Thus, problems that may be caused by strong magnetic fields are prevented.

One of the most commonly used materials are Mu-metal which contain 77% nickel, 16% iron, 5% copper and some chromium and molybdenum. Another alloy used is Permalloy.

Mu-Metal Alloys

Mu-metal is a very high permeability, nickel-iron alloy used to protect sensitive electronic equipment against static or low-frequency magnetic fields. It is a soft ferromagnetic material; It has low magnetic anisotropy and magnetostriction. Briefly speaking, magneto-strictive materials are used for materials that can change shape with a magnetic field. It converts magnetic energy into kinetic energy and kinetic energy into magnetic energy.

Usage areas of Mu-Metal Alloys:

• Electrical power transformers made with mu-metal shells to avoid affecting circuit elements
• Magnetic resonance imaging (MRI)
• Superconducting circuits
• Proximity sensors
