    Mu-metal is very sensitive to shock, and looses its shielding properties near to where it has been cut and/or bent into a tight radius.

    This might be a better choice: https://www.amazon.co.uk/YSHIELD%C2%...7WKBKTVJ1RADM3
    Have you listened to this month's choice in the Album Club?

    Yes, the best way to make magnetic screening cans is to form the metal into the required shape and then anneal it to restore its magnetic properties - not really something the DIYer can do.
    The good news is that most electronic circuits don't require magnetic screening. Mainly it's audio signal transformers that need it.
