Magnetic Shields Limited is a world leader in the manufacture of magnetic shielding technology. The company has been a major supplier to both the industrial and research communities for over fifty years and is a specialist in producing fabricated magnetic shields from the alloy mu metal. Mu metal is a nickel iron alloy that exhibits the characteristics of a very high permeability material and it is extremely effective at screening low frequency magnetic fields. With the combination of our vast experience, manufacturing techniques and equipment, we can supply the optimal product for your requirement. Whether it is a mu metal shield for a cryomodule, a fibre optic gyroscope or even a Formula 1 car, we can assist you with all stages of your project from design through to installation. All of our magnetic shields undergo a full magnetic anneal in a pure dry hydrogen atmosphere to guarantee the performance of our products, and this critical operation is conducted by experienced staff on site in our factory. In addition to the manufacture of magnetic shielding, we can also supply mumetal and other alloys in sheet and foil forms, as well as manufacture and supply high grade mu metal toroids.
