Found naturally in the Earth's crust and core, nickel is the fifth most common element on Earth. It is often found in mineral ores like nickel sulfides and laterites, and is also a significant component of meteorites and deep-sea manganese nodules. Due to its unique combination of properties, nickel is rarely used in its pure form, but rather as an essential alloying agent. Its primary use is in the production of stainless and heat-resisting steels, where it significantly enhances strength, ductility, and resistance to harsh environments. Beyond steel, nickel is crucial for various high-performance alloys used in industries such as aerospace, marine, and power generation. It's also vital in the production of rechargeable batteries, particularly for electric vehicles, and is used in electroplating for protective coatings, as well as in catalysts for chemical processes.
