uxcell Copper Sheet Roll, Metal Foil Plate 1000mm x 100mm x 0.02mm

It be copper. Looks reasonably pure to me. No complaints. A lot of the negative reviews are complaining that it's either too thick or too thin. Pro tip: check what size you're ordering. If you can't read metric, convert to freedom eagles first. Keep in mind that thin things are thin and thick things are thick.

For small electronics repair of battery contacts, I had been using some copper tape that claimed the adhesive was also conductive, but it was either very poor or non-conductive and I usually had to use it folded over so it was all copper. I think copper tape can work in a pinch for testing, but to make the fix more permanent (like replacing battery contacts), I decided to go for some actual solid copper. I wasn't sure what thickness to get, but 0.1mm is plenty compared to how razor-thin the copper tape was. This allows the copper sheet to still be flexible, easy to cut with tin snips, and flexible but not rigid nor weak. It also looks much better than the crumpled/wrinkled look of the copper tape. For more permanent fixes, I'd recommend this copper sheet if you're fixing things like battery terminals for electronic devices.

good thickness.. punches out clean for percussion caps. Stiffer than thin walled aluminum cans. maintain shape

Worked great.

Wrong size

There is not much to comment on this. It's copper, its good quality and its sturdy. Did not measure the length but the roll is heavy so there is decent amount of copper in there.

I verified the dimensions and they match the description of 1000mm x 50mm x 0.2mm. Copper was not tarnished or damaged.

I use these every time. One layer handles 40a per cell without heating up!

Quality is good, flexible. Served my purpose for which I bought it. As described in image and description.

Alles ok, danke

Clean copper, no fingerprints, no corrosion.

Excelente calidad
