Default Unsolderable wire?

I am trying to solder some RG-6 shield to a pcb. The braid won't tin.
It's
almost like it's dissipating the heat faster than I can apply it. With
both a
temp-controlled iron (set as high as 700F) and a mondo 100W stick I
finally
tried. The solder will barely melt when touched to the braid opposite the
iron.

That just sounds like another excuse to the use the butane torch


Most of the rg-6 uses aluminum instead of copper or tinned copper. The
normal methods of soldering will not work on it.


I'll believe Aluminium or steel I must admit to only a little actual
experience.
Some Cable guy should give an actual answer.



The original RG6 used a copper center conductor, and a copper braid over
a stiff, solid insulator. It was barely useful for video. The RG6/U used
for CATV has a copper plated steel center conductor, foam inner
insulator and aluminum foil covered by aluminum drain wires. If it is to
be used overhead, it has a separate stainless steel 'messenger' wire
with a Siamese outer jacket over both the coax and the messenger
strand. I worked in CATV, and used to see 50,000 feet of it come in at
a time. The best way to be sure is see who made the cable in question,
and look up the OEM's specifications for that exact type of cable.

We used Belden, Commscope, and other American made brands back in the
mid '80s.
