Copper nickel is an alloy composed of nickel and copper, and some traces of manganese and iron. Also known as cupronickel, copper nickel is highly resistant to oxidization caused by seawater. For this reason, copper nickel is considered the most suitable material for piping, heat exchangers, condensers and for the foundation and hulls of ships. It's also often used in silver and modern coins. Regardless of its high copper content, cupronickel is silver in hue.
Copper nickel is known by a variety of trade names and common names, which are typically created bsaed on its features. For instance, it is called Argentan Minargent, Alpaca, and Cuivre blanc in French, plata alemana in German, and just hotel silver. In history, it is known to Romans as an artificial type of white gold called claudianum and molybdochalcum. The ancient Greeks meanwhile called it as orichalcum.
The use of copper nickel for a variety of piping system and pipe couplings draws on the historical tradition of using cupronickel for its rust-resilient properties. The Chinese have used copper nickel for battle weapons during the Warring States Period. The Greeks, meanwhile, are the first to application it in coinage. Greco-Bactrian kings were the first to application copper nickel coins during in 180 BCE. The Chinese are also known to have used cupronickel for coinage in the form of paktong.
The West has rediscovered the application of the alloy through chemical experimentation in the Renaissance. The experimentations had proven to be rather challenging for the Europeans as the method of copying the famous Chinese paktong was more or less impossible because of the lack of required ores and pigments. Luckily though, foundries in Europe were able to perfect the process a few centuries later in the 1900s.
Marine engineering kinds of cupronickel were produced in the 1920s. The metal alloy have been first used on marine condensers during those times. Shortly after, manganese and iron were added to the cupronickel formulation as these ores were known to strengthen metals and turn them resistant to oxidization. Since the 1950s, the metal alloy have become widely produced and distributed for engineering use.
