DESCRIPTION
MuMETAL® Foil is fully annealed and used primarily in low intensity fields where the highest attenuation, highest initial permeability µ (Mu) and highest shielding efficiency are desired. MuMETAL® Foil is available in stock gauges from 0.002 in / 0,051 mm, to 0.012 in / 0,305 mm thickness.
Our most popular gauges are .002 in / 0,051 mm, .008 in / 0,203 mm, and .012 in / 0,305 mm thicknesses.
All gauges are available with optional adhesive backing on 1-side (pressure sensitive tape with release coated liner). Operating temperature range of adhesive is 32ºF to 140ºF (0ºC to 60ºC).
Foils can typically be slit to a minimum width of 1/4" (6,35mm), with or without adhesive backing. Foil width tolerance is ±0.010 in / 0,25 mm, or ±0.015 in / 0,38 mm with adhesive backing.
MuMETAL® Foil is Perfection Annealed for maximum attenuation and acceptable surface appearance. It does not require re-annealing unless severe forming or heliarc welding is performed.
Conforms to ASTM A753 Alloy 4, and MIL-N-14411C Comp 1.
Slitting, Shearing or Cutting Services: Stock foil may be slit, sheared or cut per your request.
