Reply to "Is this wire copper? The add says that it is, but I am not so sure."

I bought a box of silicone wire with that brand name on eBay a couple of years ago and it is copper clear through each strand. However you have good cause to be suspicious.  Around the same time I bought several packages of wired Dupont  connectors in which the seller called the wire copper.  Some time after I received it I was gluing small magnets on a locomotive wheel for chuff and puff control of sound and smoke. I dropped one of the small magnets and it stuck to a near by bundle of those Dupont  connectors. So I scrapped the wire with an xacto blade and sure enough the wire was steel with a very thin copper plating.  Buyer beware, even the seller may not be aware of this.       Just looked at photos and noticed from the camera perspective the bundle of Dupont connectors could have been lying flat so I added another photo looking more towards the edge of the bundle.           j
