Hoʻohana mākou i nā metala he nui i ko mākou ola, a aia nā metala i nā huahana like ʻole.keleawe keʻokeʻohe mea hoʻohui keleawe me ka nickel ka mea nui i hoʻohui ʻia.He kālā keʻokeʻo a he ʻulaʻula metala kona, no laila ua kapa ʻia ʻo cupronickel.Hiki ke hoʻoheheʻe ʻia ke keleawe a me ka nickel i kekahi i kekahi, no laila e hana i kahi hopena paʻa mau, ʻo ia hoʻi, me ka nānā ʻole i ka ratio o kekahi, ʻo ia ka α-hoʻokahi-phase alloy.Ke hoʻoheheʻe ʻia ka nickel i ke keleawe ʻulaʻula a ʻoi aku ka nui o ka ʻike ma mua o 16%, e like me ke kālā ke kala o ka alloy hopena.ʻO ke kiʻekiʻe o ka nickel content, ʻoi aku ka keʻokeʻo o ke kala.ʻO ka maʻiʻo nickel i loko o ka cupronickel he 25%.
1. ʻO ka hoʻohana nui ʻana i ka cupronickel
Ma waena o nā ʻāpana keleawe, hoʻohana nui ʻia ka cupronickel i ka hana moku, ka ʻaila, ka ʻoihana kemika, ke kūkulu ʻana, ka mana uila, nā mea kani pono, nā mea lapaʻau, nā mea kani mele a me nā ʻāpana ʻē aʻe e like me nā ʻāpana corrosion-resistant ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion a me ka hana maʻalahi. a me ka wiliwili..Loaʻa i kekahi cupronickel nā waiwai uila kūikawā, hiki ke hoʻohana ʻia e hana i nā mea kū'ē, nā mea thermocouple a me nā uea uku.Hoʻohana nui ʻia ka cupronickel non-industrial e hana i nā mea hana lima hoʻonaninani.
ʻO ka lua, e hoʻokaʻawale i waena o ke keleawe keʻokeʻo a me ke kālā
No ka mea, ua like nā mea keleawe keʻokeʻo me nā mea kālā sterling ma ke ʻano o ke kala a me ka hana.Hoʻohana kekahi poʻe kālepa hewa ʻole i ka ʻike ʻole o ka poʻe kūʻai aku i nā mea hoʻonaninani kālā a kūʻai aku i nā mea kūʻai cupronickel e like me nā mea kūʻai kālā sterling, i mea e loaʻa ai ka waiwai nui mai ia mea.No laila, pehea e hoʻokaʻawale ai i nā mea kālā sterling a me nā mea keleawe keʻokeʻo?
Ua hoʻomaopopo ʻia e hōʻailona ʻia nā mea hoʻonaninani kālā nui me nā huaʻōlelo S925, S990, XX kālā maʻemaʻe, a me nā mea ʻē aʻe, ʻoiai ʻaʻole i loaʻa i nā mea kūʻai cupronickel kahi hōʻailona a ʻaʻole maopopo loa ka māka;hiki ke kaha ʻia ka ʻili o ke kālā me ka nila;a ʻo ke ʻano keleawe he paʻakikī a ʻaʻole maʻalahi ke ʻoki i nā ʻōpala;ʻO ke kala o ke kālā he melemele keʻokeʻo keʻokeʻo, ʻo ia ka mea maʻalahi ke kala ʻana i ka oxidize, a ʻike ʻia ka melemele ʻeleʻele ma hope o ka oxidation, ʻoiai ke kala o ke keleawe keʻokeʻo he keʻokeʻo maʻemaʻe, a e ʻike ʻia nā kiko ʻōmaʻomaʻo ma hope o kekahi manawa.
Eia kekahi, inā hāʻule kahi kulu o ka waika hydrochloric concentrated i loko o nā mea hoʻonaninani kālā, e hoʻokumu koke ʻia kahi kahe keʻokeʻo like me ka chloride kālā, ʻaʻole ia ka hihia me ka cupronickel.
Hōʻike kikoʻī kēia ʻatikala i ka hoʻohana nui ʻana o ka cupronickel a me ke ʻano ʻike o ka cupronickel a me ke kālā.Hoʻohana ʻia ʻo Cupronickel i ka hana moku, ka ʻaila, ka ʻoihana kemika, ke kūkulu ʻana, ka mana uila, nā mea hana pololei, nā mea lapaʻau, nā mea kani mele a me nā keʻena ʻē aʻe e like me nā ʻāpana ʻāpana corrosion-resistant.ʻAʻole maʻalahi ke kalai ʻia ke keleawe keʻokeʻo, a he keʻokeʻo keʻokeʻo ke kala, ʻokoʻa loa ia mai ke kālā.
