A soldering question....
Posted by mini man on Monday, July 30, 2018 7:27 PM

OK soder but anyways,is it possible to solder alloy - sodacan material to...whatever  base metal that diecasts are moulded from?

I dont have a soldering iron atm so cant try it or would brazing work..

EDIT...

The vehicle in question is a Lada a 3 box designe that would be great as a limo,thinking about my future DD dio...

I'm afraid not, Nigel. Neither aluminum (sorry, aluminium) alloys nor the zinc based white metal that die-casts are made from can be soldered, and I'm quite certain that they cannot be brazed either.

Cast iron (aka diecast) and aluminum can be welded, although the thin material would be a challenge for even the most accomplished weldor.

Try JB weld, it's an epoxy like material that should work. G-day

Cast iron is a material whereas diecast is a process. The vast majority of things made with the diecast process are zinc alloys, and can be other metals/materials, though rarely (if ever) cast iron. Cast iron items are generally created through some variation of a sand cast process.

Zinc, which is a component of what is called Zamak, the alloy most commonly used for producing diecast model cars, most assuredly can be soldered, otherwise, "galvanized" sheet steel could never be soldered, and it can be.

There used to be a flux, by the name :"Salmet" whick model railroaders used to use for soldering detail parts to diecast Zamak parts, such as locomotive boilers and diesel locomotive shells.  However, it's apparently not been available for several decades now, for healh reasons, by probably the 1970's (contact dermatitis seems to be the issue there).

With the Zamak alloy (which I suspect is still being used for making diecast metal miniature cars and such) having aluminum as part of it's mix, that's the problem, at least for us laypersons who want to solder this alloy.

That said, there are some epoxies out there, in both glue and putty formats, which probably will do the job just as well, without the issues i mentioned above (found them in a quick Google search just now.

"Zamak", which is the zinc-based alloy certainly can be soldered, but it takes a special flux, which is still available, but hard to find nowadays, called "Salmet"  (stands for "Solders All Metals").  It was widely available back in the 60's and 70's, primarily aimed at the model railroad hobby, which industry produced a wide variety of  Zamak-cast locomotives and cars.
