Copper 101: Properties, Mining & Investment Resource
Cupronickel, also known as copper-nickel, is an alloy of copper and nickel, often with strengthening agents such as manganese and iron. Typically, cupronickel is 60% to 90% copper. Highly resistant to corrosion by salt water, cupronickels are often used in seawater systems and marine hardware, along with more broadly in the chemicalCopper alloys are particularly suitable for electrolytic etching, and this technique frequently gives good results with alloys (e.g., high-nickel alloys) which are otherwise difficult to etch. Solutions which have been found effective are given in Table 10.16; potential differences and current densities must be adjusted to suit specific materials..

An alloy of 25 percent nickel and 75 percent copper, essentially white in colour, was adopted for coinage by Belgium in 1860 and by the United States five years later. More recently it has been employed as the outer layer of copper-centred coins. Pure nickel was adopted by the Swiss for coinage in 1881; this use has spread to many otherNickel, with the symbol Ni, has an atomic number of 28 in the periodic table and a relative atomic mass of 58.69.
