Magnetic field shielding materials

With over 20 years of experience Dolev has the technology to meet specific requirements for any magnetic field shielding materials application.

This includes the selection of the correct magnetic field shielding materials, geometric design of the shield and determination of the best method of fabrication to meet your requirements.

Most of our magnetic field shielding materials is made from mu metal, a very high permeability material which is extremely effective at screening low frequency magnetic fields.

Mu-Metal®, in common with most of the other magnetic field shielding materials used for Shielding requires a special high temperature heat treatment.

Magnetic field shielding materials has the full capabilities to carry out this procedure in office, factory and any place you choose in order to guarantee the final magnetic properties of the shield.



With our long experience in electromagnetic engineering and metallurgical knowledge, we are able to offer a full range of magnetic field shielding materials solutions;
Dolev group has the facilities to supply all your requirements.
From individual multi layer of magnetic field shielding materials capable of screening down to the very low levels that are typically required in research applications, to high volume production runs of over 50,000 pieces a week for commercial applications.

Working in close partnership with our clients ensures that all aspects of your magnetic field shielding materials requirements are met; from prototype to manufacturing, we are here to help you every step of the way. This ensures a product reflecting the consistent high standards of quality design and value that leading manufacturers require. Dolev group is perfectly situated logistically for fast transportation of goods by air or sea to anywhere in the world.

How does a magnetic field shielding materials work?
There is no known shielding materials that can block magnetic fields without itself being attracted to the magnetic force.
Magnetic field shielding materials acts as a kind of sponge redirecting the magnetic field around the shield instead of passing through the sensitive instrument which is being shielded. a good magnetic field shielding material it must have a high permeability which means that the magnetic field lines are strongly attracted to the shielding material.

If the magnetic field is too high for the magnetic field shielding material chosen it will saturate and become ineffective. In this case you can use a multi layer shield with a combination of the above alloys. These materials should also have a very low remanence to prevent them becoming permanently magnetized.
