Magnetic Shielding Alloy Coils (Ni77/Fe14/Cu 5/Mo 4) are part of our range of nickel-iron soft magnetic alloys. With 27 variations to choose from, their properties include high permeability and low coercivity. These coils are made from alloys processed into thin foils or wire which shield equipment from stray magnetic fields. Key applications include shielding MRI machines, sensors and aerospace components from electromagnetic interference. With tailored magnetic properties, Magnetic Shielding Alloy Coils effectively concentrate and channel magnetic flux.
