"S-Bond Solder" anyone?

Just stumbled across mention of this, but that’s all I know. Claims to be a mix of materials that can allow soldering e.g. brass to aluminum.
There’s a “S-Bond 140” very low temp. solder illustrated with a picture of a big LED being soldered to something.

I tried emailing to ask about availability of small samples for hobbyist use, no answer yet.

Still sounds tricky to use with mounted components.

Aluminum and copper are readily joined by S-Bond soldering. Since the S-Bond process is fluxless the copper and aluminum can readily joined and aggressive chemical used to flux aluminum for conventional soldering to not interfere with the copper solder adherence. The process works by coating (brushing, wiping, or ultrasonic agitation) the copper, aluminum or both with molten S-Bond. Once coated, these “tinned” surfaces are slid or pressed together, while the S-Bond solder is still, after which a light load is applied and the joint area is cooled to solidify the joint. - See more at: http://www.s-bond.com/faq/#sthash.Hi56K1Kw.dpuf


I’d be happy if it would make a decent bond between brass or copper and an aluminum pill. Just wondered.

It would be great to solder a copper rod in a hollow aluminum pill.
