Cobalt is a steel-gray shining metal that shows a close relationship to iron and nickel but it is stronger and harder. Cobalt is ferromagnetic at room temperature. Due to its characteristics, cobalt forms very corrosion-resistant alloys with many elements.
Cobalt is an important alloy metal for corrosion resistant hard metals in turbines/ engines, chemical plants and in diamond tools due to its characteristics. It is also a component of magnetic alloys as well as lithiumions-high-performance electricity storages.
