| GROUND wire won't tin... Not a noob question. |

I hate duct tape, it's one of those products that does a whole bunch of things poorly and almost nothing very well, for everything it gets used for there is a better product out there. It leaves a nasty sticky mess all over everything. |

I've seen CAT5 cable with copper plated aluminum wire that will tin once. If you try again the copper comes off and you will never get solder to stick again. |

Coke Zero works as flux on that shit. Smells awful though. |
| Rerouter:
Aluminium can be soldered, you just need the flux to cover a decent area, the flux is wanting to rip the oxide off, you just need to make sure it cannot reform, and solder will take. I've soldered steel and aluminium many times just by going overkill on the rosin flux, once its changed translucent and spread, scrape the base metal through the flux with a pick, then bring in the solder and it will bite at the scrape marks and spread, You will however see a very odd mix of colors on the surface of the flux, it looks like a grey mud on aged aluminium. You will have to be prepared to get that joint hotter than a normal copper joint. Up to a certain point the flux gets more aggressive at higher temperatures. Also never use plumbers flux, sure the acid helps, but aluminium leaves some voiding in the alloy, and still forms skins of partial oxide unless you give it a silly amount of time to dissolve in the lead, so you get trapped little droplets of acid. |
