Propiedades del níquel: desde monedas hasta aleaciones y más allá

Nickel, with atomic number 28 and symbol Ni, is a shiny, ductile metal used since 3500 BC. It was classified as an element in 1751. Nickel is used in coins, alloys, and various industrial applications due to its corrosion resistance. It forms alloys like stainless steel and cupronickel, used in marine environments. Nickel is also found in batteries, magnets, and everyday items. While not essential for humans, it supports plant growth and is safe in small amounts.
