Extreme Heat for Extraordinary Results
As a final operation before it is a finished (and effective) magnetic shield, our high permeability mumetal and medium permeability Alloy 49 magnetic shields need to be heat treated to restore maximum magnetic permeability. The heat treatment process must keep the alloy pure to optimize magnetic shielding performance so we use a retort hydrogen furnace for all of our in-house heat treating. This style of furnace allows us to ensure quality and maximum permeability for all of the magnetic shields we produce for our customers. Vacuum heat treating will also yield similar results and is used for larger magnetic shields as well.
If you already have a fabricated mumetal or Alloy 49 magnetic shield, MuShield offers contract hydrogen heat-treating. Send us a drawing at info@mushield.com or call 603-666-4433 to discuss your hydrogen heat treat needs.
