About Nickel
Nickel is rarely used in its purest form. Most nickel is combined with other metals to form alloys. As a transition metal, it combines readily with other metals, especially iron, chromium and copper, to produce alloys with particular combinations of properties that cannot be achieved by pure metals:
- Alloys of iron, nickel and chromium can be formulated to combine strength and ductility with resistance to corrosion in various environments. The most widely known of these alloys is stainless steel, which is used in transportation, construction and in industrial applications in the chemical industry and in oil and gas engineering, where the environment can be very corrosive.
- Other alloys of nickel, chromium and other metals have been developed for very-high-temperature strength and corrosion resistance. These alloys are used in jet engines and in industrial gas turbines for electricity generation. They are also used in heater elements, resistance wires, heat exchangers in power plants, furnace components and industrial pumps and valves.
S'all good, people!
