Foils/Sheets/Cable Shields
MuMETAL® Stress Annealed Sheet
High-Performance Magnetic Shielding for Sensitive Applications
Unmatched Shielding Performance in Low-Intensity Magnetic Fields
Precision stress-annealed for formability, ideal for fabrication of enclosures, cylinders, cans, and custom 3D shielding boxes.
The Fabrication Journey of MuMETAL® Shields
MuMETAL® Stress Annealed Sheets are partially annealed for ease of machining, bending, and shaping. These sheets must undergo final Perfection Annealing after fabrication for maximum magnetic performance.
1
Raw Material
High-grade MuMETAL® alloy is designed for high initial permeability and shielding efficiency in low-field environments.
2
Cutting & Forming
Sheets are cut and shaped into custom forms like boxes, cans, and shields using standard fabrication tools.
3
Welding or Stamping
Parts are joined or formed to meet precise enclosure designs. Post-fabrication annealing is recommended to restore shielding properties.
4
Final Annealing
A critical step—perfection annealing in an atmospherically controlled environment maximizes magnetic properties and shielding performance.
5
Inspection
Each shield is checked for dimensional integrity, surface condition, and material thickness uniformity.
6
Packing
Sheets and finished parts are carefully packed to prevent damage or deformation.
7
Dispatch
Parts are dispatched to meet your timelines-ready for integration in critical applications.
