Mu metal shielding is a component that protects fragile systems from the ill effects of excessive feedback or sudden charges. Many electrical applications contain numerous tiny, fragile components, that are easily marred by interaction with unstable currents, or other electrical interference. Due to the properties of these fragile components, they cannot simply be permanently secured by affixing them to a specific place in the device, as they are often components that need to be changed or adjusted.

Because of its ability to secure sensitive components without interfering with the electrical flow, mu metal shielding is often used with devices that contain delicate components inside a harsh environment. A prime example of this would be in certain types of audio equipment, where fragile components are placed in danger to audio feedback, and the electrical disturbances that occur as a result. This also holds true for video equipment, as well as for audio devices.

Mu Metal Shielding Composition

The main component in mu metal shielding is an alloy, comprised mainly of nickel and iron, and containing some molybdenum and copper as well. This alloy creates an encasement that can be placed around sensitive components, yet contains properties that prevent it from interfering with the operation of the areas it is protecting. This is the result of the properties of mu metal shielding, which allow it to have a low conductivity rate, yet be highly stable.

Some of the most common uses of mu metal shielding are lab applications, where it assists to maintain the stability of an experiment scenario. One example of this is when it is used to shield vacuum chambers during experiments with low energy electrons. Another common use is visual electronic imaging, where it helps to maintain the stability of precision devices, such as oscilloscopes and other medical devices. It does this by protecting the magnetic resonance imaging components of these devices, without interfering with the desired flow.
