Nickel is a silvery-white lustrous metal with a slight golden tinge, corrosion-resistant.
Core Principles & Analysis
Axel Fredrik Cronstedt isolated nickel in 1751 from the ore miners called 'kupfernickel', or devil's copper, because it yielded no copper.
The ferromagnetic metal resists corrosion and, alloyed with iron, makes up most of Earth's core; the iron-nickel alloy Invar barely expands with temperature.
About two-thirds of nickel production goes into stainless steel, with the rest in coins, electroplating, rechargeable batteries, and hydrogenation catalysts.
