The physical and chemical properties of cobalt determine that it is an important material for producing heat-resistant alloys, hard alloys, anti-corrosion alloys, magnetic alloys, and various cobalt salts. E like me ka mea e hoʻopili ai i ka powder metallurgy, hiki iā ia ke hōʻoia i kekahi pale kū'ē i ka cermend. ʻAʻole i pōkole nā ​​alloys Afloys i nā mea i nā mea hou ma keʻano o nā electrisitings a me nāʻoihana electromechanical a me nāʻoihana electromechanical. Hoʻohanaʻia lākou e hana i nāʻano likeʻole no ke kani, mālamalama, uila, ka uila a me ka magnetisty.

ʻO Cobatt kekahi mea koʻikoʻi nui o nā alloys mau loa. In the chemical industry, in addition to high-temperature alloys and anti-corrosion alloys, cobalt is also used in colored glass, pigments, enamel and catalysts, desiccants, etc. According to relevant domestic reports, the use of cobalt in the storage battery profession, diamond stuff profession and catalyst profession will also be further expanded, so that the demand for metallic cobalt is on the rise.
