Confirmed copper by measurement

There are many fake "copper" wire products on Amazon these days, which are not actually copper. Some are even supposedly tinned, but what is inside may be an alloy of copper like brass, so you can't even trust color or color of the cut ends of the wire. This wire, as of April 2021 at least, is actually copper, per 4 wire resistance measurement using Kelvin clips. A 10 foot piece of 10 gauge should read .01 ohms, and this wire does.
