Yes good point , did they make tin covered copper in stranded? That’s good to know if they did , we concentrate so much on single strand - solid aluminum , just assumed the multi stranded type was aluminum. Probably is tin covered then.

A sharp knife and you can scratch the surface and see it is copper under the tin.
Yes they did make tin plated stranded copper and still do
