Cobalt Plate Sheet

The use of cobalt-based alloys containing 20% -27% chromium in structural materials of aircraft turbines enables the material to achieve high oxidation resistance without the need for protective coatings. Nuclear reactor heating Mercury makes the thermal medium turbine generator can run continuously for over one year without overhauling. It is reported that the boiler used in the pilot of the United States is made of cobalt alloy. Cobalt is one of the few metals that can retain its magnetism once it is magnetized. Under the action of heat, the magnetic loss temperature called Curie point, Curie point of iron is 769 ℃, nickel is 358 ℃, cobalt up to 1150 ℃. The magnetic steel containing 60% cobalt has a 2.5-fold increase in the coercive force than the conventional magnetic steel. Under vibration, most magnetic steels lose almost a third of their magnetism, whereas cobalt steels lose only 2% to 3.5% of their magnetism. Therefore, the advantages of cobalt in magnetic materials are obvious. Cobalt metal is also widely used in electroplating, glass, dyeing, medical and medical applications. Lithium cobalt oxide made of lithium carbonate and cobalt oxide is the most commonly used high-energy battery cathode material in modern applications. Cobalt may also be used to make nuclear weapons, a theoretical atomic or hydrogen bomb, contained in a cobalt shell that explodes to turn dead cobalt into radioactive dust.
