ʻO Cobalt he metala kila-hina ʻālohilohi, ʻano paʻakikī a palupalu, ferromagnetic, a like me ka hao a me ka nickel i ka paʻakikī, ka ikaika tensile, nā waiwai mechanical, nā waiwai thermodynamic, a me ka hana electrochemical.Nalo ka magnetism i ka wā i wela ai i 1150 ℃.ʻO ka pauka cobalt metala maikaʻi i hana ʻia e ke kaʻina hana hoʻemi hydrogen hiki ke hoʻā koke i loko o ka cobalt oxide i ka lewa.Hana ʻia ka oxidation ma nā wela kiʻekiʻe.Ke hoʻomehana ʻia, hana ikaika ka cobalt me ​​ka oxygen, sulfur, chlorine, bromine, etc., e hana i nā pūhui like.Hiki ke hoʻoheheʻe ʻia ka Cobalt i loko o nā ʻakika hoʻoheheʻe ʻia a hoʻopaʻa ʻia i loko o ka waikawa nitric fuming ma ka hana ʻana i kahi kiʻiʻoniʻoni oxide.Hoʻopili mālie ʻia ʻo Cobalt e ka waika hydrofluoric, ammonia a me ka sodium hydroxide.He mea koʻikoʻi ʻo Cobalt no ka hana ʻana i nā mea hoʻoheheʻe wela, nā ʻāpana paʻakikī, nā ʻāpana anti-corrosion, nā alloy magnetic a me nā paʻakai cobalt like ʻole.He metala amphoteric ka Cobalt.

ʻO nā waiwai kino a me nā kemika o ka cobalt e hoʻoholo ai he mea waiwai nui ia no ka hana ʻana i nā ʻāpana pale wela, ka carbide cemented, nā ʻāpana anti-corrosion, nā alloy magnetic a me nā paʻakai cobalt like ʻole.Hoʻohana ʻia ke kila kila i hoʻokumu ʻia i ka Cobalt ma ke ʻano he mau pahi, impellers, conduits, jet engines, rocket engines, missile parts a me nā ʻāpana wela wela nui i loko o nā mea kemika a me nā mea metala koʻikoʻi i ka ʻoihana ikehu atomic.ʻO Cobalt ma ke ʻano he mea paʻa i ka pauka metallurgy hiki ke hōʻoia i ka carbide cemented i kahi paʻakikī.ʻO nā alloys magnetic nā mea waiwai nui i nā ʻoihana uila a me nā ʻenehana electromechanical hou, i hoʻohana ʻia e hana i nā ʻāpana like ʻole o ka acoustic, optical, uila a me nā mea hana magnetic.ʻO Cobalt kekahi mea koʻikoʻi o nā alloy magnetic mau loa.I ka ʻoihana kemika, hoʻohana ʻia ka cobalt me ​​nā superalloys a me nā mea hoʻohui anti-corrosion, akā no ke aniani kala, pigments, enamel a me nā catalysts, desiccant a pēlā aku.Eia kekahi, ʻo ka hoʻohana ʻana i ka cobalt ka mea ulu kiʻekiʻe loa ma ka ʻāpana pākaukau.

Hoʻohana nui ʻia ka cobalt metala e hana i nā ala.He hua'ōlelo maʻamau no ka hoʻokahi a i ʻole kekahi mau alloys i hana ʻia me ka cobalt a me ka chromium, tungsten, ka hao a me ka nickel.Hiki i ke kila kila me ka nui o ka cobalt ke hoʻomaikaʻi maikaʻi i ka pale ʻana a me ka ʻoki ʻana o ke kila.ʻAʻole e nalowale ka carbide Starlite i ʻoi aku ma mua o 50% cobalt i kona ʻano paʻakikī ʻoiai inā i wela i 1000 ° C, a i kēia manawa ua lilo kēia carbide i mea nui loa i hoʻohana ʻia ma waena o nā mea hana ʻoki gula a me ka alumini.I loko o kēia mea, hoʻohui ʻia ka cobalt i nā ʻāpana carbide metala ʻē aʻe i loko o ka hui ʻana, i ʻoi aku ka paʻakikī o ka alloy a hoʻemi i ka naʻau i ka hopena.Hoʻopili ʻia kēia huila a hoʻopaʻa ʻia ma ka ʻili o nā ʻāpana, hiki ke hoʻonui i ke ola o nā ʻāpana e 3 a 7 mau manawa.ʻO nā mea i hoʻohana nui ʻia i ka ʻenehana aerospace ʻo ia nā nickel-based alloys, a hiki ke hoʻohana ʻia nā alloys cobalt-based, akā ʻokoʻa ka "mechanics ikaika" o nā ʻāpana ʻelua.ʻO ka ikaika o nā nickel-based alloys i loaʻa ka titanium a me ka alumini he kiʻekiʻe ma muli o ka hoʻokumu ʻana o kahi mea paʻakikī paʻakikī i haku ʻia me NiAl (Ti), ke kiʻekiʻe ka mahana hana, ua hoʻololi ʻia nā ʻāpana mea paʻakikī paʻa i ka hopena paʻa, a laila ka pau koke ka ikaika o ka alloy.ʻO ke kūpaʻa wela o nā mea hoʻoheheʻe cobalt ma muli o ka hoʻokumu ʻana o nā carbide refractory, ʻaʻole maʻalahi e hoʻohuli i nā hopena paʻa, a liʻiliʻi ka hana diffusion.Ke piʻi ka mahana ma luna o 1038 ° C, ua hōʻike piha ʻia nā mea maikaʻi o nā alloys-based cobalt.No nā ʻenekini kiʻekiʻe, kiʻekiʻe-mehana, nā mea hoʻohui i ka cobalt i kūpono.
