winding wire

[Lostcause]

Anyone know where (in the UK) to get solid 1mm silver wire with insulation suitable for winding some 'small' torroids?

I'm in the UK as well so I'd be interested to hear what you're up to or how you get on.

I've been busy with coiling electromagnetic pickups and such. I had a stack of links to wire manufacturers and was talking to a lot of them about buying spools of silver wire. But I can't seem to find them in my favourite now (list is gigantic now, needs major cleaning).

I know that Hi-Fi Collective sell plated and solid silver wires but the solid wires are pretty expensive. Their 99.9% pure 1mm solid silver wire is about ten pounds per meter without vat.

Also, there seem to be a lot more manufacturers outside the UK than there are in it. Might be worth paying a bit more in postage for wider choice and a lower price per meter.

Maybe you could get away with using lower purity wires in the power transformers, like 99% or plated, to save some cash. I'm assuming you're thinking of winding power transformers but perhaps not.

According to Wiretron you could get about 7.75 amps through a 1mm (18AWG) copper wire safely. I think pure silver is about 8% more conductive, go with 7 for safety. Which should mean a 1mm pure silver wire could carry ~8.29 amps safely and continuously at a rough guess. Obviously, inrush current is only going to heat the wire for a second or two so if you have an inrush at 8 amps I expect it would be fine.

After messing around trying to wind thousands of turns of 38 - 40 guage wire by hand onto tiny bobbins and then creating layers within those bobbins, 1mm onto a toroid would be relaxation by comparison!
