Cryogenic Shields

Cryogenic Magnetic Shielding      


In recent years Nickel Iron manufacturers have worked to produce high permeability grades of material suitable for magnetic shielding that can maintain good levels of permeability down to 4 degrees Kelvin.

This development is very significant in high energy physics and other superconductor applications. It means that a functioning shield can be inserted inside the cryogenic system, improving functionality and providing economical reductions in both space and cost.


Magnetic Shields Limited have been constructing shields in this material for a number of years and have developed considerable expertise in the special heat treatment required to develop the optimal low temperature magnetic properties. 

Please Contact Our Technical Sales Team if you have any requirements for technical advice, sample shields or sheet supply of this specialist material.
