Curious on something. My yard said that coax cable like from the cable company, is more steel than copper. That I should throw it in the tin pile.

Now some I agree, because a magnet will stick to them. But I have some other coax, that a magnet wont stick too. It actually has somekind of aluminum sheath under the plastic, then what appears solid copper. I even cut the wire, and still shiny copper.

Please clarify
