No metal actually "turns green", although copper and possibly others develop surface layers that are green when exposed to many natural atmospheres.
Copper turns green when it reacts with sulphur (sulfur) in the air, forming copper sulfide.
There are some "aluminium bronze" alloys which contain aluminium copper with a small amount of iron and other metals- these are mainly copper with 4-8% aluminium and ess than 1% of other metals.
Alloys made by mixing metals together often have more desirable properties than pure metals. Pure gold, for example, is very soft and easily damaged. Bronze, an alloy of copper and tin, is also harder than pure copper.
The Mesopotamians combined copper and tin to make bronze. This mixture of metals produced a stronger and more durable material than either copper or tin alone.
Copper alloys are more useful than pure copper because they have enhanced properties such as increased strength, hardness, and corrosion resistance. By combining copper with other metals, alloys can be tailored to suit specific applications, making them more versatile and suitable for a wider range of uses than pure copper.
In industrial wiring 'three phase' green or bare copper is the norm for a ground. In home wiring 220/110 single phase, bare copper is the ground

Copper is a more scarce material than most other metals.

It might be newer than copper or less tested because this metal has been mixed with other metals such as iron
Gold and Copper Are the only colored metals other than different shades of gray and black and whatnot
Brass is harder than some metals like aluminum and copper, but not as hard as others like steel or titanium.
Most likely, metals are in your water. If your pH is low (less than 7.0) and you have a heater with copper tubing, or some other source of metals, you may have copper dissolved in your water. Have your local pool supply store test for metals and if the test is positive, use a chemical like "Metal Free" at a rate of one liter per 20000 gallons.

Copper cannot displace metals that are more reactive than itself. Examples include Sodium, Aluminum, Iron, Magnesium, etc.
Its OK: most metals are good conductors -------------------------------------------- More: since a nickel is made out of copper and nickel then it is sure to be a good conductor. ------------------------------------------------------------------------ More Information: Pure nickel is not a very good thermal conductor compared to other metals like copper. Nickel is often mixed with other metals, such as copper, and those alloys often have better thermal conductivity than pure nickel.
Yes. They do.******Contrablue Adds:Unfortunately, this is often incorrect. Many metals are found in chemically "bound" form in their ores -- that is, they are in the form of salts or other compounds rather than the shiny metal. For example, copper is often found in the form of copper carbonate, which is a beautiful green mineral (pure specimens are called "malachite"). But malachite doesn't have a shiny luster because the copper is chemically bonded to oxygen and carbon!The only metals likely to be found "native" or in the uncombined, shiny state, are noble metals such as gold or platinum.The answer is True
Metals like gold, platinum, and silver typically do not react with copper sulfate. Additionally, metal compounds that are less reactive than copper, such as zinc oxide or aluminum oxide, will not react with copper sulfate either.
