Two types of copper or some other metal?

[powerbuy]

I have collected a large quantity of what appears to be copper coil.... my question is as to the difference between the two colors of copper.... one is quite red in color while the other is the traditional copper color. Are these both copper? Anyone know what the difference is or what causes the extreme color difference between the two? Pictures attached....

What your seeing is a coating ment to keep low voltage discharges from putting carbon pits into wire winds.

The color is part of the series. The Coating is colored to show the ammount of insulation it can provide.

for instance I can tell by the gauge and shade of the coating that the purple wire came from a transformer, and the other from a hard drive.

Clear coating is used for voltages 1 - 5, Purple is used for transformer winds about 50 - 600 volts.

Thank you for your quick answer! I'm sure I am showing my ignorance with questions like these, but I am fairly new to the whole scene. So as far as recycling value goes, they both are valued the same?

Getting to know your basic elements better would be a good start.

:roll: lol I will though, if you got any other silly ones send me a private message,

I don't recommend that idea. For starters, others often benefit by questions that are commonly posed by newbies, assuming they are made publicly------plus, and this is most important----the opinion of one individual often is not correct----so idiotic notions are promoted endlessly by keeping the "knowledge" (which would be better ignored) underground. There's more than enough of that going on right now in refining----thanks to idiots that promote recovering of values using AR when processing plated copper alloy materials.

By posting misinformation, others that may know better have the opportunity to make corrections, hopefully eliminating the possibility that poor habits are formed by those seeking advice. It is my recommendation to always ask questions publicly. If you choose to rely on a single opinion, insure that the respondent has good credentials. Know-it-all types are often misinformed.

I although I do know quite a bit, I don't presume to know everything. If i find something I cannot answer with a factual answer I will tell that person so.

I myself just recently started here and can tell you most of the members here won't even answer a question as basic as this.

What planet have you been on?

I personally don't mind. He answered quickly and in detail and it was very much appreciated!

Ok! What is being insulated copper or aluminum.

A junkmans best friend a pocket magnet, the scrap yards give away one that fits on your keychain. Another must would be a pocket knife or file for scraping through insulation or painted goods.

As a kid I swipped a roll of copper from the railway ( 340 lbs ) the cops were waiting at the top of my climb. Its amazing how much weight one is able to pack on their shoulders with a bit of help getting it there. The steep climb did me in. I had turfed the roll of wire half ways up, the cops retrieved and weighed the evidence.

The aerial tram operator at Hells Gate made the call, to further insult to injury there was another joke to be played out.

The railway used a copper clad steel wire, which did not make any difference to the judge. in passing sentence.

You missed the point. A quick answer has no value if it's wrong.

Mind you, I'm not suggesting that his was----but I've yet to meet anyone that knows everything, although I have known more than my share that think they do----including a person that used to be my closest friend. He'd gladly give you answers to almost anything-----but when you spoke in areas in which I had expertise, it was obvious he didn't know what he was talking about. From that I concluded that he likely didn't know what he was talking about in general. It's called credibility. Once it's lost, a person's opinion is valueless.

Not good enough.

What you consider to be "factual" may indeed be nothing more than a figment of your overactive imagination. I see you are highly complimentary of your own knowledge, but that has yet to be proven here on this board. I lost my oldest and likely best friend to an attitude just like yours. He knew everything, even when he didn't have a clue.

That's exactly why newbies should ask questions publicly (they should also prepare themselves to understand answers they will receive by reading the basics of precious metal refining)----to avoid finding someone that thinks they know everything, when they don't. Not suggesting, not even for a moment, that you are this person---but you are new here and have shown the board only that you can be very irritating at this juncture.

It's flat amazing how a board can have been in existence, as this one has, for 1½ years, and functioned perfectly well without you-----then you come along and want to re-invent the wheel, telling us how it should be.

Let me give you a little friendly advice. It's something like "when in Rome"---- Learn to talk with these people as if they have a modicum of intelligence. That includes those of us that moderate. You will quickly wear out your welcome if you persist in trying to prove yourself to be a leading authority in an area in which you openly admit you have no knowledge.

Say, by chance, could your name be Sue?

Am I well within my right to be offended?

If your interested the specific details on the type of inductive coatings and varnishs can be found in this book.

Thats Bibliography entry from a paper I had to read during one of my courses. It comes complete with Citations and works referenced.

Just didn't want to have my credibility at stake.

As I said, you were not being accused of providing misleading information in this case. What you are advised not to do is encourage readers to exclude their questons from the board. It is here to serve all readers, not to act as your pesonal sounding board. In order for you to become a welcome member of this group, you must comply with certain rules of behaviour. Setting yourself aside as a leading authority isn't one of them.

My patience with you is running thin. Be advised.
