Is the copper in copper wire a pure substance (element or compound) or a mixture (homogeneous or heterogeneous)? Copper is an element, which is a pure substance. The gases oxygen and nitrogen have a uniform composition in nitrox, which makes it a homogeneous mixture.
Is copper wire really copper?
Because commercial purity has improved over the last century, copper conductors used in building wire often slightly exceed the 100% IACS standard. This copper is at least 99.90% pure and has an electrical conductivity of at least 101% IACS. ETP copper contains a small percentage of oxygen (0.02 to 0.04%).
Are copper wires a mixture?
In the case of copper wire, pure copper wire (meaning without any other metals or substances) is a homogeneous substance. If the copper wire is a mixture (meaning that it contains other metals to improve the physical properties of the material), then that mixture is also likely to be homogeneous.
Is it worth stripping aluminum wire for scrap?
If you come across Insulated Aluminum Wire when scrapping, it is a good idea to strip it down to make some more money with it. Usually if you take the time to strip it you can make upwards to $0.30 more per pound with the clean aluminum wire you get from it.Jan 2, 2022
How much is cable wire worth?
Is copper wire element or compound or mixture?
Typically, copper wire is an element because it purely consists of copper. However, in rare cases, copper is mixed with other elements to increase the strength of the wire and it becomes a homogeneous mixture.
What wire is worth stripping for scrap?
The most valuable type of scrap copper wire is bare bright copper. This uncoated and unalloyed copper is stripped of insulation, paint, and other impurities, making it easy to reuse or recycle. As such, it is usually the first thing that scrap buyers look for.Nov 1, 2019
Is Thhn wire worth stripping?
If you have a large quantity of THHN Cable, it may be worth it to strip it for the bare bright wire inside. Most of the time we don't see too many people stripping this type of wire though because it is so thin, that it isn't always worth the time.
Is Romex wire worth stripping?
By stripping the Romex® Wire you can make between 10 and 30% more money depending on what level of time and investment that you put into it. Through talking to multiple scrappers over the years we have found that about 50% of people sell as is and 50% will strip it down further.Jan 2, 2022

What kind of substance is copper wire?
(a) Copper wire is a metallic element.
Is copper a mixture?
So copper is a pure substancepure substanceHydrocarbon, a category of substances consisting only of hydrogen and carbon.https://en.wikipedia.org › wikiHC - Wikipedia in any form (only copper atoms). Things that have different types of atoms or molecules, not arranged in regular patterns, are typically called mixtures. Vodka, for example, has some ethanol molecules and some water molecules, mixed together in an irregular, changing pattern.
Copper wire is composed of one element, copper, Cu. If the wire contains other metals to modify its properties or lower its cost, the copper then is one component of a mixture, formed without the occurence of a chemical reaction. Mixtures can have any proportions/ratios of components.
What is considered dirty aluminum?
Dirty aluminum is any type of aluminum with steel, rubber, or plastic attached. There is added labor attached to any aluminum scrap that has to be cleaned by the scrapyard workers. That is why you will receive the “dirty price” when you bring in items with other material attached to the aluminum.Mar 3, 2021
