Did not test tinned wire, but I drilled a couple of tinned lugs and it was copper underneath the Tinning.

Just make sure it isn't CCA, copper clad aluminum. Tinned is actually better, since it resists corrosion. If they don't say copper, assume it is CCA.

You might want to use a reputable vendor rather than trusting random strangers on ebay.

Tinned copper wire is good. There is some stuff that is tinned over some alloy, not copper, which should be avoided.
