Foils/Sheets/Cable Shields
MuMETAL® Foil
High-Permeability Foil for Maximum Magnetic Shielding
Ultra-thin, fully annealed. Ideal for shielding low-frequency magnetic fields where space and flexibility are critical.
Used in medical, laboratory, audio, aerospace, and industrial applications for precision electromagnetic shielding.
Flexible Shielding for Complex Applications
MuMETAL® Foil is our highest-performance shielding material, fully annealed for maximum initial permeability and attenuation. Designed for versatility, it provides a "ready-to-use" solution for low-frequency magnetic environments, including DC and 50/60 Hz fields.
Benefits
Why Choose MuMETAL® Foil?
1
No Re-Annealing Required
Unlike standard sheets, our foil is magnetically optimized and ready to perform immediately, unless subjected to heavy forming or welding.
2
High Shielding Efficiency
Offers extremely low coercivity and the highest permeability available in a flexible form.
3
Versatile Application
Thin enough to wrap, layer, or line confined spaces; easily adheres to flat or curved surfaces.
4
Protective Packaging
All foils are precision-rolled and boxed to prevent contamination or deformation during transit.
Standard MuMETAL® Foil Sizes
Available per linear foot. Contact us for volume discounts.
