Cobalt is a slightly magnetic, tough, lustrous heavy metal. With us, you can buy high-quality cobalt at the best price and receive the goods quickly.
It only melts at high temperatures of about 1495 °C and is used for heat-resistant steel coatings. In its elemental form, cobalt occurs only very rarely. However, it is part of many minerals, although usually only in small quantities. Cobalt is obtained primarily from copper and nickel ores.
Cobalt is a steel-gray metal with atomic number 27 and the element symbol Co. In its properties, it resembles nickel and, as an alloying metal, transfers these characteristics to the metal to be alloyed. Cobalt counteracts coarse-grain formation, increases wear resistance, and promotes magnetic properties.
Cobalt is used as an alloying metal for hard metal, high-speed steel, and hot-work tool steel. It has good creep resistance. In combination with nickel and copper, it enables use as a high-temperature material. In addition, cobalt can be used to produce martensite-hardening form steel. In pure form, cobalt is used as a heating conductor material. It is corrosion-resistant in humid air and against water.
By far the most important application of cobalt is the production of rechargeable batteries, followed by superalloys, hard metal and diamond tools, magnets, and various other chemical and metallurgical applications.
