    Just as the title says: Can nickel be soldered?

    My customer now wants to enclose my circuit within a nickle plated brass tube. Now brass solders just fine thank you but will nickel accept solder?

    (Dang my process guy is in Pennsylvania!)

    The obvious answer: try it.
    I don't think so, but that's why I say, "try it".

    Can an aluminized steel oil pan be brazed? Right after you scrape off the aluminum.
    Can sub-C nicads be soldered? Right after you violate the coating with a diamond file.
    Can nickle coated brass be soldered? Right after you file the nickle off.

    Read my signature line.

    You might consider using a permanent adhesive, something like J-B Weld (not J-B Quick). It's one of the few good ones that you can pick up just about anywhere, and good over quite a wide temp range.

    At a former employer, we had some "old pros" that did a very nice job soldering nickel-plated brass enclosures. They used large American Beauty soldering irons that put out plenty of heat, and usually Sn63/Pb37 solder.

    I wouldn't even try soldering a brass tube using your typical small iron; the tube would wick the heat away too quickly.

    yes it can with an agressive flux application. We solder some nickle plated brass quick connect tabs at work. With enough/aggressive flux it works just fine.

    Thanks fellows. Picture a rectangular PCB wedged inside the metal tube from a pencil eraser. That's about my situation and I solder one point on the board to the tube for electrical contact.

    On my prototypes I used nickel plate on brass, but the plating did not extend into the tube so I was esentially soldering onto brass. I did try soldering direct on the outside of some extra tubes but the solder didn't have a good "flow." Heat is not as issue as I have lots of heat at my disposal, protos got reflowed with a hot air pencil.

    Production will be with a stamped tube, possibly solid nickel, and I was wondering if that would be trouble.

    Thanks for the assist!
