Magnetic shields are leading specialists in the manufacture of bespoke mumetal magnetic shielding and the supply of mumetal sheet foil and bar.
Mu metal sheet uk.
Mu metal is a 80 nickel 4 5 molybdenum balance iron soft ferromagnetic alloy which means that it does not retain a field after the removal of an external magnetizing force.
Mu metal sheet magnetic shields are a leading supplier of magnetic shielding sheets.
