Stress Annealed | Final Annealed (Perfection Annealed)
MuMETAL® is typically stocked in a stress annealed state to allow further
fabrication, stamping, severe forming or welding. During fabrication, a
material's
grain structure is weakened. After final fabrication processes are completed,
grain structure is then modified by controlled atmospheric annealing to relieve
stress in the material, resulting in larger grain structure, softer temper, and
ultimate shielding performance. Although MuMETAL® is available in many forms,
most shields are fabricated from foil or sheet
stock. |
