Copper is a reddish-coloured metal. It is a pinkish colour when it is new, but turns a reddish orange colour after it is exposed to air. It is very flexible and ductile. That means that it can be stretched into wires easily. It is also very soft, it has a Moh’s hardness of 2.5 to 3. That means that it is harder than a fingernail but softer than a steel pocketknife. It is also one of the few coloured metals. Most metals are grey or silver. Gold, copper, and osmium are the only three coloured metals.
When sold as scrap, there are many different terms used for describing the various different grades. All grades, you can sell as scrap metal to make money.

Like aluminium, copper is 100% recyclable without any loss of quality, regardless of whether it is in a raw state or contained in a manufactured product. In volume, copper is the third most recycled metal after iron and aluminium. It is estimated that 80% of the copper ever mined is still in use today.According to the International Resource Panel’s Metal Stocks in Society report, the global per capita stock of copper in use in society is 35–55 kg. Much of this is in more-developed countries (140–300 kg per capita) rather than less-developed countries (30–40 kg per capita).
The process of recycling copper is roughly the same as is used to extract copper but requires fewer steps. High purity scrap copper is melted in a furnace and then reduced and cast into billets and ingots; lower purity scrap is refined by electroplating in a bath of sulfuric acid.
