Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.
21 hours ago · Cobalt is used to produce high-performance alloys that exhibit favorable mechanical properties. Cobalt is used in making superalloys that are resistant to corrosion, wear, as well as temperature. The basic composition of most cobalt alloys is cobalt and chromium where chromium acts as the strengthening agent.

Introduction. - Cobalt is a hard, metallic element symbolized as Co with an atomic number of 27. - This transition metal is crucial for various applications, such as rechargeable batteries, superalloys, and pigments. - As a metal, it is solid at room temperature, silvery-blue in color, and has magnetic properties.
Uses. Cobalt, like iron, can be magnetised and so is used to make magnets. It is alloyed with aluminium and nickel to make particularly powerful magnets. Other alloys of cobalt are used in jet turbines and gas turbine generators, where high-temperature strength is important.
