Bergquist and Thermagon sell copper-clad boards that can be etched and drilled more or less like FR-4, but that have a thick 62 mil inch slab of aluminum or steel rather than the typical 1.4 mil (1 oz) or 2.8 mil (2 oz) copper.

Maybe you could ask them to substitute mu-metal for your board ?

(1 mil = 0.001 inch = 25.4 um)
