The only bronze that I know of that would give trouble would be like an Oilite bushing, because of the oil in it.I have not tried bronze
Nah ... the joint will neither be flexed or suffer vibration. And the amount of current will be quite low, and also the voltage. That's why it's important that I don't use stainless steel for these screws, so as to keep power losses to a minimum.If the joint receives any flexing I would look at low temp silver solder using a small torch. Especially if any significant current flow.
Max.
Thanks for the advice, but I wasn't planning on doing things that way. My plan is to solder the wire to the head of the screw. The flat bottom of the screw's head will be pressing against the acrylic, with an o-ring between them acting as a sealant.Yes, they do, but it is not a good idea to do so. A sufficiently tightened screw should be enough to guarantee an airtight joint. Don't depend on solder to do this (as we have discussed many times here).
Actually, Bronze is an alloy of copper and tin, while Brass is copper and zinc.You asked about bronze. You DO know bronze is an alloy of copper and brass. Therefore, the answer regarding bronze would also be "Yes".
Actually both tin and copper are solderable, so I don't see any problems with soldering bronze (provided the alloy is just those two elements).It's the presence of tin and zinc in those alloys that had me wondering if they'd affect common electronic solder.
Oops. Yes. You're right. I'm wrong. Disregard my comment please.Actually, Bronze is an alloy of copper and tin
Once again, Danko, you've reached the heart of my question.It is easy to solder bronze, but for brass you need to use flux like this:

After soldering wash thing with water.
You are welcome!Once again, Danko, you've reached the heart of my question.
Many, many thanks!
Subtleties like that make my day!(strategically-placed vias allowed the solder to flow to the top surface of the board to solder the nuts to keep them from turning).
Thanks for the warning, somewhere in the back of my head that's information that I had already learned, many years ago. Thanks for bringing it back to the surface. On the other hand, it is magnet wire that I'll be soldering, so the effect that you're describing will not be a problem, and the joint is something that I can easily wash after soldering.Zinc chloride leads to a perpetual corrosion cycle - chlorine is a powerful oxidant and will react readily with the metal.
