Can you Make a Faraday Shield out of Copper?

[Greg Trook]

I was wondering if copper can be used as a Faraday shield for a coil? I'd like to be able to solder a solid connection to it. Aluminum is difficult to get a good, reliable, weatherproof connection to as it can't be soldered that I know of. I have some copper mesh I could use. Any reason that would not work? It has a mesh size similar to fly screen. Any input appreciated.

You can solder to aluminium with the correct solder. I use Multicore Alu-Sol. It's fine for foil and low-grade alloys, but no use for anything slightly exotic.
There is a school of thought that says if you can solder to it, it is too conductive. Favoured materials include graphite-coated paper sheet, with surface resistivities from 1kOhm per square up to 10kOhm. This should be achievable with a soft artists pencil, eg. 6B type.
There are several threads on this forum on this topic, search and you will find references to foils, meshes, copper, aluminium, lead, allsorts. Hope this helps.

Thanks I appreciate that.

I use scotch #24 shielding tape which is tinned copper mesh. I would imagine your copper mesh has a good chance of working
