Re: soldering to nichrome wire

I am trying to solder copper wire (tinned) to nichrome ribbon (more like
wire, but wider), which I took from an old toaster. The nichrome ribbon
doesn't seem to like the solder. Is there a trick to this? Or should I be
doing something to the nichrome before I try to solder it? On the toaster I
dismantled, I noticed it was soldered to some thick copper conductors, so I
didn't think it would be a problem. I even crimped the ends of both, hooked
them together, and soldered them. After a time I picked up the connection
and it fell apart. Any advice or help is appreciated.

Multicore has a couple of types of solder wire with aggressive fluxes,
also available through Farnell. Their "Arax acid" is claimed to be
suitable for brass, bronze, iron, spring steel and resistance wire.
They also have an "AluSol" product for aluminium, but they say it
solders virtually all metals, including stainless steel.

Make sure you clean the flux residue really well.
