[Boatanchors] Milliammeter shunt resistance wire sources?

[Ron]

I have flux available that works well on stainless steel typically wets
battery tops in an instant for those who do not have tabbed batteries
and need to make a replacement pack. 
Also works well on the watch batteries used in many radios for the back
up memory.  Not using the flux and you end up destroying the battery
before it gets wetted with solder. 

I have not tried it on nichrome but I suspect it would work.
