Cobalt (chemical element)

Cobalt is a hard, shiny metal with a blue-gray color, known for its strength and resistance to corrosion. It is a transition metal used mainly in producing strong, durable alloys for jet engines, electronics, and medical implants. Cobalt also has special properties, such as maintaining magnetism at high temperatures and supporting the production of vibrant blue pigments used in paints and ceramics. Naturally, cobalt is found in the Earth's crust often combined with other elements, and it is primarily obtained as a byproduct of mining other metals like nickel and copper.
