[TowerTalk] Teflon Coax with Center That's NOT SCCCS?

I did not realize until Jim's post that RG-142 has a steel center. I also
use RG-400 which has a copper conductor and it works great. I use 75 ohm
Teflon coax on 80m, now I am wondering what the conductor is made out of.

Silver plated stranded center

1" bend radius

.195" OD

50 ohms

Choice by many for chokes
