I see some potential problems. If any of the components contain a
ferrous metal, then inductive heating would be a problem. Also, iron,
if memory serves has a problem with oxidization. I wonder how they
bond the iron with the other elements to avoid this. maybe it needs
to have conformal coating. What's the price tag going to be for the
solder, and the inductive soldering equipment?

Assuming not 01 April issue and genuine. By implication the iron is not
going to rust and break down the joint any more than Pb in SnBp will
oxidise/ionise and dissolve/breakdown. How many Tesla to make a joint in
close proximity to chippery?

Nope. Not an April issue. Internal link to an external paper sent via their
weekly e-newsletter. Generally, Elektor are not given to publishing
non-genuine material, and it seemed pretty feasible to me.

As others have mentioned, I smell a potential rust problem. Near as I
can read between the lines, the iron is used as a filler to increase
strength and does not chemically bond or alloy with the other
ingredients. That would imply that just about any strong conductive
metal might work. Stainless perhaps?

My current favorite solder is 96% tin and 4% silver. Very expensive
and 220C (430F) melting point.

Also, Tin-Lead-Bismuth mixes, which melt as low as 138C (280F).

Well, Tin-Lead-Bismuth-Silver is more practical at 170C (338F).

my fav is 63/37 eutectic. Not lead-free,though.

the solder in Chip-Quik SMD removal kit(Sony?) melts at 160degF. (FWIW)

Is that made from Woods metal , the stuff they make thermal fuses and
fusible resistors from and also joke teaspoons, despite containing cadmium
and lead.

I'm not sure,IIRC,Sony kept the formula private.
It probably has indium and bismuth in it,I doubt it has cadmium.
