Technical characteristics
Cobalt is a hard metal that has two modifications: The α-modification is stable up to t° 427 °C, and the β-modification (cubic face-centered lattice) is stable at t° 427 °C - 1120 °C. Cobalt is a ferromagnet with a Curie point of 1121 °C. Cobalt bar has remarkable mechanical strength and corrosion resistance.
