Dear All
Any budding electrical engineers/metallurgists/chemists etc out there? Hope you can help me?
Quite a while ago I bought on a well known auction site some twin , red/black copper wire for general use ,
speakers etc
All was well for a while till they went faulty...traced it to the wiring and both wires were faulty , so replaced them...all was well for a while again till....
So , after ripping the wiring out again , had a closer look at the cable and it seemed the copper wire was " disintegrating " for want of a better word , which brings me back to a problem a couple of years ago when I had problems sealing hydraulic fittings , mult-ipacks of various copper O rings were found to be steel , copper plated , so now I carry with me a small magnet....won't be caught out again!!
Back to the copper ? wire , how can one tell if it is copper wire or as suspected copper plated aluminium wire ?
Thanks
John

Buy from reputable sources Eg VehicleWiringProducts or carbuildersolutions.
In terms of what you're stuck with, sandpapering the ends will reveal the colour underneath.

Not copper, but brass - years ago I bought a whole load of (fairly expensive) solid brass screws also off a well known auction site, since I was fed up of steel going rusty.
They looked good, they looked like brass - years later I was using one and the hole was slightly too small as when I turned the screw in, it ground off the brass to reveal steel underneath
As I've just ordered copper speaker wire from the same auction site (before seeing this thread) I can't help but wonder now what metal it'll be made of since it was very-very cheap
