Mu Metal Sheet
Magnetic Shields Limited is a leading manufacturer of magnetic shielding components and supplier of soft magnetic alloy sheet materials and has over fifty years’ experience in this market.
These types of alloy typically present the highest permeabilities combined with the lowest coercive forces and magnetic losses in the low frequency range.
With the largest stock of shielding materials in Europe, we can supply mumetal in gauges ranging from 0.35mm to 5mm in sheet form and many different gauges in foils down to 0.05mm thick.
We carry a large stock of cold rolled, stress annealed mu metal (80% Ni) to ASTM A753-97 Alloy 4 specifications, which is also complimented by smaller ranges of cryogenic mumetal, 50% Ni, 36% Ni and pure iron.
All of these materials are stress annealed for fabrication purposes and should receive a final anneal to achieve optimum magnetic properties after fabrication. Magnetic Shields can offer a full range of hydrogen heat treatment services and can supply sheet in final magnetic anneal condition in restricted lengths. If you wish to purchase sheets in this condition please consult our sales team for information on the maximum length that can be heat treated in one piece and advice on suitability for your particular application.
Magnetic Shields Limited is a registered ISO 9001:2008 company and all materials can be supplied with complete certificates of analysis and conformity upon request.
In addition to the supply of sheet material, foils, tubes and wires, Magnetic Shields can offer full in-house production of fabricated components including final heat treatment.
