Copper foil


I just recently started a DIY project and wanted to know if anyone knows of a copper foil distributor or manufacturer. I am looking for .0075 thickness which is hard to find. Also, if you have info using the copper foil I am curious how you are using it in your system.

Thanks

Foils is lowsy leaders compared to thicker circular or other shapes. Might look exotic but ruins soundquality used as cables. Foil conductors on the other hand gives a clean sound, and many seems to mix that up not realising why they sound cleaner.

Foil conductors. Anyone know of a designer who builds silver or copper foil for IC's?
Nordost, Goertz, Mapleshade, Allen Wright/VSE are a few. McMaster-Carr sells raw electronics-grade copper and there are several small distributors of silver foil.
From what I undertand "foils" might be easier to use in speaker cable designs than in interconnect designs.
