Copper ? Wire
Posted: Sun Jan 12, 2020 1:59 pm
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 , multi-packs 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
