Review on Bryne Flexible Silicone Temperature Resistance by Chuck Chen

Compared to a real 18AWG wire, it appears to be 18. While it may be slightly smaller, it could also be due to thinner strands versus thick lugs. on the wire I compared to. But it seems to me 18GA. The wire inside is also made of copper with a tin coating. I scraped off the plating to make sure it was copper. Because I hate aluminum wires. Very flexible wires, I really like the silicone coating. Should work fine for connecting some stitches to the relay as you don't need extra thick wire for that.
