Soldering Zinc

Does anyone know the correct tools/methods for soldering zinc sheet. I’ve been told that it can’t be soldered when it’s cold outside because it will crack. Regular solder doesn’t seem to work or solder as easy as regular copper or lead coated copper.
Anyone have any ideas?

  1. I bet you are having trouble with the solder you are using. The ZD PRO FLUX will make his life easier. Also Zinc has a melting point about half that of copper…he should use propane and a torch. No problem soldering in the cold, but bending is an issue. He may consider fabricating inside until warmer weather. Radiuses should be watched. Rule of thumb:1 1/2 times the thickness of the material thickness.
