Looking to purchase some Mu Metal but

  1. Jul 2, 2013 #1
    It's so expensive!
    I've received a few quotes.
    1st quote was 12 inches wide by 12 inches long by .01 thick. 50$ I need 3 feet of that size. But wow that's expensive for a material that's 75-80% nickel.

    2nd quote was 4 inches wide by 12 inches long by .01 thick. 27$ I would need 9 feet at that width.

    I mean this is really over priced! On eBay they have some mu metal that's cheaper but it has a sticky adhesive on one side that I really don't want.

    Does anyone know or have any experience purchasing mu metal? If so could you give me some info on where to get it for a reasonable price?

    Thanks

    I've been satisfied with Magnetic Shield Corporation:

    I doubt that they are cheap, but I think their prices are competitive. Also, be careful where you buy your mu-metal shields. If they've been stressed mechanically, they lose much of their high-mu character. They need to be annealed at high temperature after any mechanical forming or manipulation.
