uses of cobalt

The metal is used in electroplating because of its appearance, hardness, and resistance to oxidation. Cobalt deficiency in animals, especially ruminants, can cause diseases such as decreased digestive capacity and anemia, so trace cobalt is widely added to animal feed. Cobalt is only in the body as part of vitamin B-12. (Cobalt Periodic) Cobalt is a part in a lot of steels, specifically in super alloys. In this article, we’ll introduce 7 uses of cobalt you mightn’t know. The following uses for cobalt are gathered from a number of sources as well as from anecdotal comments. Cobalt improves the performance of rechargeable batteries and plays an important role in hybrid electric vehicles. Cobalt is used in electroplating for its attractive appearance, hardness, and resistance to oxidation. Cobalt is a transition metal.It is shiny and conducts electricity. Cobalt alloys are widely used for aircraft engine parts, as the high temperature strength is an important factor. Under the vibration environment, the general magnetic steel loses almost 1/3 of its magnetism. Adding an appropriate amount of cobalt to penicillin can improve its curative effect. In vitamin B12 (alias cobalamin), which has special effects on hematopoiesis, the cobalt content is as high as 4.5%. Cobalt was also used to colour glass in the Chinese Tang dynasty from 618 AD. If you want to know more about the cobalt or other refractory metals, you can visit Advanced Refractory Metals (ARM) for more information. Radioactive 60 Co is used in the treatment of cancer. In addition, cobalt is also used in artificial joint materials and dental fillings. Cobalt salts are used to impart blue and green colors in glass and ceramics. Therefore, the cobalt-based alloy is widely used in the aerospace and modern military fields. Cobalt-60 is used in the inspection of materials to reveal internal structure, flaws, or foreign objects and in the sterilization of food. Cobalt chloride, sulfate, acetate or nitrate can correct mineral deficiency in grazing animals living on cobalt-deficient soil. Cobalt is used in electroplating, a process in which a layer of material is applied to an object to give it a particular aesthetic or protective quality. The Idaho Cobalt Project states that approximately 70 percent of hip replacements use cobalt-chrome femoral stems. Cobalt-60 is used in medicine as it produces gamma rays. Cobalt combines other metal carbide grains in the alloy composition to make the alloy tougher and reduce the sensitivity to impact.

Cobalt is also used to make alloys for jet engines and gas turbines, magnetic steels and some types of stainless steels. Stellite hard alloys containing more than 50% cobalt will not lose their original hardness even if heated to 1000 ℃. Cobalt (Co), chemical element, ferromagnetic metal of Group 9 (VIIIb) of the periodic table, used especially for heat -resistant and magnetic alloys. Alloys of cobalt make up half of global cobalt use each year. Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military applications, many of which are strategic and critical. I would be delighted to receive corrections as well as additional referenced uses.. alloyed with iron, nickel and other metals to make Alnico, an alloy of unusual magnetic strength with many important uses (jet engines and gas turbine engines) Cobalt has some of the same jobs as manganese and zinc. Cobalt compounds can be used as catalysts in the petrochemical industry and as adhesives in the rubber tire industry. Some alloys go into making jet engines and gas turbine engines. Required fields are marked *. Cobalt has had and still has many uses in the world today. Uses of Cobalt Cobalt is used in alloys for aircraft engine parts and in alloys with corrosion/wear resistant uses. Although these naturally found alloys have interesting uses and properties, cobalt can be added to other elements like tungsten, nickel, and samarium to form superalloys. Cobalt is a hard gray metal element. As previously mentioned, cobalt is usually found as an alloy within the earth. Now that we know what cobalt is and some its cool properties, let's look at some uses of this metal. It is also used as catalysts for the petroleum and chemical industries. Cobalt-60, a radioactive isotope of cobalt, is an important source of gamma rays and is used to treat some forms of cancer and as a medical tracer. Due to its appearance, hardness and resistance to corrosion, cobalt is often used in electroplating. Thank you for reading our article and we hope it can help you to have a better understanding of the uses of cobalt. Alnico magnets can be found in hearing aids, compasses and microphones. It is also is specifically made for use in gamma irradiation plants – it is not a waste product of nuclear power plants. These magnets are used in hearing aids, microphones and compasses. The large role cobalt plays in cathode technology is, in part, why the EU and the USA class cobalt as a critical raw material. Currently, nearly 40% of cobalt … Under the vibration environment, the general magnetic steel loses almost 1/3 of its magnetism. Iron has a Curie point of 769 ° C, nickel of 358 ° C, and cobalt of 1150 ° C. The magnetic steel containing 60% cobalt has a coercive force 2.5 times higher than that of ordinary magnetic steel. Due to its good temperature resistance, corrosion resistance, and magnetic properties, cobalt is widely used in production and our life. The radioactive isotope of cobalt can treat skin diseases and malignant tumors. COBALT MAY NOT BE RARE, BUT IT IS VALUABLE. It is used in all of these industries in many ways.
