Nickel and Copper are often found together because nickel and copper have the same densities so when they are layered together between other minerals, they layer into one category

Is nickel a good thermal conductor?
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.
What form is copper most commonly found in?
It is most often found in the carbonate mineral malachite.
What is cuprinickel?
The word is cupronickel and it's just what it says, a combination of copper and nickel.Cupronickel alloy is often used for coins. For example, the outer cladding of US dimes, quarters, and halves is an alloy of 25% nickel and 75% copper; British 20p coins are 84% copper and 16% nickel while 5p, 10p, and 50p coins are 75/25; Australian 5, 10, 20, and 50-cent coins are also 75/25.
Can silver tarnish into green?
Sterling silver contains a little over 7% copper and silver plate often has a base of copper or an alloy containing copper. Copper corrosion and some copper salts are green, as in the popular verdegris patina on outdoor copper scupture or roofing. I have found green corrosion on some of my silver plate, which I believe is copper sulfate and due to the reaction of sulphur compounds (found in many foods and also found in newspaper, so don't pack silver in newspaper!) with copper exposed by the wearing away of the silver plate.
What is the alloy of gold?
Gold is often alloyed with other metals to make it harder or change its colour. Some alloys:- rose gold made with copper, white gold made with either nickel or palladium,
Is copper nickel free?
Copper itself is one of the elements. It contains nothing but copper. It might be alloyed with nickel sometimes, but that would not always be the case.You may be thinking of the fact that nickel was sometimes found mixed in with copper ore. Its hardness compared to that of copper caused such problems for miners in Saxony that they called it "Kupfernickel", a German word that translates roughly as "Devil's copper". Eventually the "Kupfer" prefix was dropped, giving us the word we use today.

In what form is copper found in nature?
Occasionally as elemental copper but more often as a sulfide or an oxide.
What form is copper most commonly found in?
It is most often found in the carbonate mineral malachite.
How is cobaltite extracted?
Cobalite is cobalt that has been extracted from copper and nickel. The mixture is often heated and treated using flash smelting techniques, and often, the mixture is boiled to get it to separate.
What does the word nickel refer to?
It's a shortened form of the German expression Kupfernickel, which is usually translated as "devil's copper".German miners gave the name to the hard, difficult-to-work ore that they often found while looking for copper. Nickel's usefulness didn't become important until better mining and smelting techniques were developed.
What is the most valuable scrap metal?
Most people would say Copper because it is worth ~ $3.00 per pound as scrap. The truth is, however, that pure nickel scrap is worth more than pure copper scrap, namely $8-$9 per pound. Nickel is much harder to find though, so people don't think to answer nickel. Cupronickel in a mixture of copper and nickel, like what is used to make coins. This copper nickel alloy is often used in silver-plate. This is often worth more than the value of pure copper. That being said, any metal can be scrapped. So technically that includes rare and precious metals like gold, platinum and rhodium. But I don't think you were inquiring as to the worth of those.

What types of metal are involved with plating services?
Many metals can be used in plating, such as copper, nickel, silver, gold and chrome, which is often used on cars.
What would cause a 1941 war nickel to look copper?
To clear things up, 1941 nickels aren't war nickels. The US didn't enter WWII until December of that year, and war nickel production didn't start until 10 months later. All 1941 nickels were struck in the standard alloy of 75% copper and 25% nickel, so a copper-colored coin could result from exposure to heat or chemicals. In particular, nickels are often copper-plated in high-school chemistry experiments.
Nickel is often used in electric wiring because of its superior ability to conduct electricity and its relatively low cost?
false I agree copper can oxidize and cause problems nickel is applied to limit oxidation and usually is a coating not as solid wire.
