Get effective protection against low-frequency magnetic fields
If you need to protect sensitive equipment or spaces from disturbing, low-frequency magnetic fields, mu-metal shielding is one of the most effective options. Mu-metal is a special EMC material - a nickel-iron alloy - used for its unique ability to absorb and dissipate magnetic fields that might otherwise affect electronics or create interference.
What is mu-metal and how does it work?
Mu-metal acts as a protective shell around what you want to protect. Instead of blocking the magnetic field completely, the material guides the magnetic field around the protected area, preventing interference from reaching it. This is particularly important for low-frequency magnetic fields, where common metals like copper or aluminium do not provide sufficient protection.
Then you should choose mu-metal shielding
- For electronics and devices sensitive to magnetic fields, such as measuring instruments, medical equipment, audio systems or hard drives.
- In environments where you want to reduce the risk of interference, such as laboratories, hospitals, server rooms or near power lines and transformers.
- When you need a material that is mouldable and can be adapted to different shapes and sizes. Mu metal can be produced as sheets, casings or enclosures, depending on what you need to protect.
Why mu-metal is so effective
Mu metal has extremely high magnetic permeability. This means that it is much better at conducting magnetic fields than other, more common metals. In order for the material to work optimally, it requires special heat treatment, and it is important that it is handled correctly to maintain its protective properties.
Frequently asked questions about mu-metal shielding
What is mu-metal shielding?
- It is a special metallic material that shields against low-frequency magnetic fields, often used around sensitive electronics and equipment.
When do you need to use mu-metal?
- When you want to protect equipment or rooms from disturbances caused by magnetic fields, for example in laboratories, hospitals or near power lines.
How does mu-metal work as a magnetic field shield?
- Mu-metal guides the magnetic field around the protected area, so that interference does not reach what you want to protect.
Can mu-metal be customised for different needs?
- Yes, mu-metal can be made in different shapes and sizes, as sheets, enclosures or casings, depending on what you need to protect.
