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.

∙ 10y agometal detecting i found a copper nickel with green all over it don't know the year it has to be cleaned.does any one anything that would help me. thanks adam

∙ 12y agoCopper and nickel are different elements; as such, pure copper is nickel free.

∙ 12y agoNo, nickels are 75% copper and 25% nickel.

∙ 10y agoGenerally not; but copper-nickel alloys are very known and used (for examples thermocouples with constantan).

Why wouldn't Nickel replace copper in copper II sulfate?
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
Why is iron magnetic and nickel or copper is not?
nickel and copper are elements that can be magnetized
Is nickel a better conductor than copper?
No - copper is a better conductor than nickel.
How does the nucleus of a copper atom compare to the nucleus of a nickel?
copper has more protons than nickel
How does the nucleus of a copper atom compare to the nucleus of the nickel atom?
copper has more protons than nickel
What is a 1949 nickel made of?
It is made of copper and nickel. A 1949 NICKEL is made from copper & nickel.
Why is iron magnetic and nickel or copper is not?

Why wouldn't Nickel replace copper in copper II sulfate?
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
Is a nickel less dense than a dime?
Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.
What are modern day nickels made of?
mostly copper and nickel. a nickel is made mostly of copper. in fact, it is 75% copper and around 25% nickel!
What is the density of copper nickel?
Copper-nickel is an alloy of copper and nickel which have different densities. You need to know the proportions of each metal in the alloy to determine its density.
Is nickel a better conductor than copper?
No - copper is a better conductor than nickel.
What is an alloy of copper and nickel called?
cupro-nickels, there exists a range of different copper nickel alloys that possess different properties and hence are suited to a range of different applications. Some of the better known copper nickel alloys include: · Copper with 10% nickel · Copper with 30% nickel · Copper with 25% nickel with 0.05-0.4% manganese · Copper with 45% nickel (also known as constantan) All copper nickel alloys consist of only one phase as the copper nickel binary system exhibits complete solid solubility.
