    On a less powerful scale the process is used in necking or reducing
    the size of tubing for heat and coiling coil applications. And for
    crimping assorted sized small motor and other metal/plastic or metal
    to metal assemblages or equipment. The advantage of the pulsed
    magnetic field is in a necking machine by controlling the pulse you
    don't need a set of dies for each of the different dia sizes there
    by cutting and keeping cost down. 

    And the distortion is a normal result, when a force is applied to
    metal no matter what form the force is in. (Heat, bending, striking,
    (shrinking and stretching sheet metal body work)) As the web site J
    D provided has stated. The reaction to the power will be different in
    each metal and the bond between them. And the other thing is they
    are two separate quarters, with differing wear and abuse patterns
    etc. For a photo side by side comparison.
