dollar store wire...

[legg]

The local dollar store is offering various materials aimed
at decorative or other consumer grade applications - wood,
adhesive, paper, plastic film, wire etc.

Some of the wire coatings might be suited to short-term
use, in a pinch, if the wire material itself is usable.

Saw 2mm dia AL the other day ( in six colors . . . .),
for which twisted pairs could be hipotted to >2500V.
Allowing for low temperature index, mechanical fragility
and unknown chemical resistance, they have a limited
immediate functionality, in a pinch.

Most useful item I\'ve found at dollar store was \"tea light
holders\". Small footprint, reasonably deep (volume) and,
in this case, outward flared rim -- perfect for collecting
screws and other small parts you don\'t want to misplace when
working on something!

The solid copper wire sold for jewelry makers, tin or gold plated, is
super hard and is a bad electrical conductor, not annealed and
probably not all copper. Electrical grade bus wire is much more
expensive.

And, the \'bronze\' wire for sale is sometimes bronze-colored
aluminum, which might be fine for jewelry, but terrible for
winding springs. Bronze wool, sold as a nonrusting wood-finishing
item, is real springy bronze, though. I\'m currently making my springy
battery connects with a shrinking length of bronze music wire...

It\'s probably a cheap metal with tin/ copper plating to make it solderable. Dunno how it could be a bad conductor.

Yes, but it usually doesn\'t solder well either.

Good annealed copper has conductivity almost 6e7 S/m.

Brass is about 28% as conductive as copper. Some bronzes are as low as
7% as conductive as copper.

Any additive to copper wrecks the conductivity.
