Tinned wire is only a plus in corrosive environments (salt air/water, or actual corrosive areas, where you'd probably need some other insulation anyway.)

Lots of other applications still need wiring. They're buying stuff for everything from houses and schools to satellites.

Yes, but would they use non-tinned in a boat even though they might be bulk ordering for elsewhere?


I decided to see how this stuff is to work with. Horrible!

Just a few layers to get through

Heat shrink terminals, covered in adhesive heat shrink tubing, and at the base, a little black 5200 under a larger piece of 1/2" adhesive lined heat shrink.

Thinking this might hold!

If you use glue line heat shrink to seal joints in wiring and avoid any exposed wiring where water is present then copper is fine. For example I recently got a set of Lenco tabs fitted and all the wiring they supply is not tinned. However with Deutsche connectors at the rear where the cables join it will be fine.

Also most of the electronics you get have copper looms (not tinned).

If salt water gets in then tinned or copper will corrode.

You're talking about the military. Who knows what they might do?

Looks like a good job.

As an FYI, if you shave off a bit of a hot-glue stick and stuff it in with the wire, you end up with adhesive lined heat shrink tubing, even if it wasn't adhesive lined. Cheaper than using 5200.

Interestingly, I chose Lectrotabs instead of Lenco and they came with tinned wire. I agree that there is still alot of standard copper wire used in the marine environment, not least in engine looms. However, I would much prefer to use tinned on anything I fit so that it is one less thing to worry about in the future. I prefer a fit-and-forget approach rather than wondering when or if it might fail.

Ya, the heat shrink already had adhesive in it but I just wanted to fill the void when I put the large piece of shrink at the base of the two wires and I had a resealable 5200 sitting around.

Good to know for next time though!

A couple of drops of the "liquid electrical tape" inside the end of iffy connectors works great. I use this when I have 2 wires in one connector or similar situations (had to do this on my trailer wiring recently)

You can clean this cable up with a white vinegar and salt solution...
Only recommended if you really can't replace it though...

White vinegar and salt?

While it may clean up the corrosion, I'd be a little leery of a) introducing an acid to what is already a reactive metal, and b) adding more of what caused the corrosion in the first place. Going to be impossible to rinse the stuff out of the strands, in any case.

The blackened cable that I've seen has been completely rotten - even the strength had gone and it was brittle. The problem isn't surface tarnishing (that wouldn't effect the conductivity) - it's the complete degradation of the copper in the wire. Poly will know what the reaction is - is it forming a salt or something?
