Title: Where do I find thin copper strips? (rectangular wire)
Post by: Glenn0010 on February 16, 2024, 01:47:25 pm

Hi all,

I'm looking for thin copper strips/ rectangular wire, ideally in the range of 0.1 to 0.3 mm thick and 2-4 mm wide. Had a search but can't seem to find a supplier. I need this for a planar coupled inductor

Does anyone have an idea of where I could find this? Bonus points if it supplies to the UK.

I have a 130W C02, 10570-10640 nm laser cutter available, but don't think this is ideal for cutting copper. But may try if I can't find what I need.

Cheers Glenn

If that doesn't work, go here and search for "tape"

Maybe you can find a local jeweler with a Durston or similar rolling mill. They work great for rolling round copper wire into flat wire.

Look for copper foil tape on Amazon and elsewhere.  Cut with scissors or tin snips.
