Mumetal metalwork

  1. Mar 23, 2013 #1
    Hello ! I'm going to use thin ( 0.004" ) sheet of Permalloy-80 to realize a magnetic shield ( against european 50 Hz mains ). I have to bend this sheet to give it a 6" radius curvature. I would like to know if this treatment will not dammage and annihilate the magnetic properties of this material.

    Bending a thin sheet so gently should not change the material's properties.

    I have used mumetal to make 2 enclosures one with a 14cm radius and one about 8. The material seems to be performing well
