He aha nā ʻano nui o ka pā keleawe keʻokeʻo?

I ko mākou ola i kēlā me kēia lā, e hoʻohana mākou i nā huahana metala he nui.Nui nā huahana metala he synthetic.ʻO kapepa keleawe keʻokeʻohe keleawe keleawe me ka nickel ma ke ʻano he mea nui a ʻaʻohe mea.Ma muli o ke keleawe-nickel alloys, ua hoʻohui ʻia nā koʻokoʻo cupronickel me nā mea ʻekolu e like me ka zinc, manganese, aluminika, etc.Hoʻokaʻawale ʻia ʻo Cupronickel i ʻelima mau ʻāpana: cupronickel maʻamau, kīʻaha hao, cupronickel manganese, cupronickel zinc a me cupronickel alumini.
ʻO ka pāpaʻi keleawe keʻokeʻo maʻamau ka nui o ʻehā mau ʻāpana e like me B0.6, B5, B19 a me B30.ʻO nā mea maʻamau ʻo B19 a me B30, a ʻoi aku ka nui o nā māka ma ke kūlana ʻAmelika.ʻO ke koʻokoʻo cupronickel he hāʻina paʻa mau i hana ʻia e Cu a me Ni, me ka lattice cubic alo, e like me ia i hōʻike ʻia ma ke Kiʻi 1-18.Ke emi iho ka mahana ma mua o 322 degere, ʻo ka Cu-Ni phase diagram he ākea ākea ka ʻāina wela no ka decomposition metastable, e hoʻohui ana i nā mea ʻekolu e like me Fe, Cr, Sn, Ti, Co, Si, Al a Cu-Ni alloys etc. ., hiki ke hoʻololi i ka haku mele ʻana, ka pae wela a me ka wahi o ka decomposition metastable, a hiki ke hoʻomaikaʻi i kekahi mau waiwai o ka alloy.
Loaʻa i ka cupronickel maʻamau nā waiwai hana anu a wela.Hiki ke hana maʻalahi i nā ʻano like ʻole e like me nā papa, nā ʻāpana, nā paipu, nā koʻokoʻo, nā ʻano, a me nā uea.Maikaʻi kuʻihao hana, hiki e palupalu, brazing, kinoea shielded arc kuʻihao a me ke kū'ē kuʻihao, etc.;ʻO ka hana ʻoki ʻana he 20% o kēlā o ke keleawe ʻoki manuahi HPb63-3.
ʻO ka pāpaʻi keleawe keʻokeʻo maʻamau he kūpaʻa corrosion maikaʻi, ikaika waena, plasticity kiʻekiʻe, hiki ke hana ʻia e ke anuanu a me ka wela, a me nā waiwai uila maikaʻi.Ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he mea hana, he mea koʻikoʻi ke kūpaʻa kiʻekiʻe a me ka thermocouple alloy.
