Electrically conductive adhesive

Can anyone suggest an electrically conductive adhesive suitable for joining two metals, copper and steel. Mechanically negligible stress and conductivity need not be all that high - current in micro-amps.

how about RS (rswww.com) item 496-265 it's a conductive epoxy according to RS it "Bonds a wide variety of materials including solder alloys, aluminium, copper and glass" not sure about steel - it =A323+delivery+vat

you could also try item 186-3616,not sure what the difference is expect it is =A345+del+vat

No, I've already wasted far too much time when the damn things go wrong.

Join it with an adhesive, then apply an electrical bond _separately_. There are plenty of silver-loaded paints around, from RS to Halfords.

When I used to do this regularly (load cells) the final answer involved epoxy, then a looped bridge of thickish polyester (Mylar) glued in place as strain relief, then the conductive track painted over the bridge. Anything else was just too unreliable in service -- and we didn't even have _that_ much vibration to worry about.
