As nā mīkini hoʻonani gulamea hana, kaʻana like mākou i ka ʻike no nā mea hoʻonani gula no nā mea kūʻai aku.

Hoʻohui ʻia ke gula me nā metala e like me ke keleawe a me ke kālā i ka wā e hana ai i nā mea hoʻonani. ʻAʻole he mea ke gula keʻokeʻo i loko ona iho, akā he gula wale nō i hui pū ʻia me nā metala ʻē aʻe e hana i kahi ʻano kālā. ʻO nā metala i hoʻohana pinepine ʻia i ke gula keʻokeʻo he nickel a me palladium, a i ʻole zinc a tin paha.

KA HOʻOHUI ʻANA I NĀ MEA HOʻOHUI NO KA HANA ʻANA I NĀ MEA HOʻONANI

Ua ʻike anei ʻoe i nā metala āu e ʻaʻahu nei?

E kahaha paha ʻoe i ka ʻike ʻana i ka nui o nā metala like ʻole a me nā mea hoʻohuihui i komo i loko o kāu mau mea hoʻonani a ma kou kino. Ma William Rowland, haʻaheo mākou e hāʻawi i nā metala maʻemaʻe kiʻekiʻe a me nā mea hoʻohuihui i nā ʻano ʻoihana like ʻole a puni ka honua.

ʻO nā ʻano metala nui a mākou e noʻonoʻo ai i ka wā e pili ana i ka hana ʻana i nā mea hoʻonani he kālā a me ke gula, akā ʻo ka ʻoiaʻiʻo, ʻaʻole i hana ʻia ka hapa nui o nā mea hoʻonani i ke kālā maʻemaʻe a i ʻole ke gula. ʻO ke kumu o kēia, ʻoiai ma ko lākou ʻano maʻemaʻe loa, ua palupalu loa ke kālā a me ke gula ʻaʻole kūpono no ka hapa nui o nā mea hoʻonani. Loaʻa i nā metala āpau nā waiwai kūikawā e kūpono ai lākou no nā hana kikoʻī, a ʻo ia ke kumu he mea nui e kamaʻilio me kahi mea kālepa metala akamai i ke kauoha ʻana.

ʻO ke ʻano kālā maʻemaʻe loa ua kapa ʻia ʻo 'kālā maikaʻi' a hoʻohana nui ʻia kēia no ka bullion, ma mua o nā mea hoʻonani a i ʻole ke kālā, ʻoiai he palupalu. He maʻalahi loa ke kala i ka palaho, a ʻo ka hui ʻana me nā metala ʻē aʻe e pale aku i kēia. Akā, hoʻohana ʻia kahi mea hoʻohuihui, kālā sterling. He 92.5% ka maʻemaʻe o kēia, akā ua hui pū ʻia ke koena me nā metala ʻē aʻe e like me ke keleawe, ka zinc a i ʻole ka silicon.

Pēlā nō, ʻo ke gula ma kona ʻano maʻemaʻe loa e mālama pinepine ʻia no ka bullion, ʻoiai he palupalu a maʻalahi ke ʻano ʻē i nā mea hoʻonani a i ʻole ke kālā. Hoʻohui ʻia ke gula me nā metala e like me ke keleawe a me ke kālā ke hoʻohana ʻia e hana i nā mea hoʻonani. ʻAʻole he mea ke gula keʻokeʻo i loko ona iho, akā he gula wale nō i hui pū ʻia me nā metala ʻē aʻe e hana i kahi ʻano kālā. ʻO nā metala i hoʻohana pinepine ʻia i ke gula keʻokeʻo he nickel a me palladium, a i ʻole zinc a tin paha.

Aia kekahi mau hui like ʻole o ke gula e hana i nā kala a me nā hopena like ʻole. ʻO ke gula Rose ka hui ʻana o ke gula melemele, ke kālā a me ke keleawe, e hana i kahi waihoʻoluʻu poni, a ke ʻike mau ʻia nei nā hui metala hou no nā mea hoʻonani.

Ma Hasung ua ʻike mākou i ka metala a ma muli o ka hana ʻana i nā lako metala makamae mai ka makahiki 2000, loaʻa iā mākou kahi ʻike kūikawā o ko lākou mau waiwai a me nā kūpono no nā ʻano hana like ʻole. Ke kūʻai ʻoe i nā metala ma o ka mākeke, inā paha ma ke kau ʻana i kahi kauoha ma ka hale kūʻai pūnaewele, a i ʻole ma ka hui metala kūloko, e hōʻoia e loaʻa iā ʻoe nā metala kūpono, ma ka hoʻohana ʻana i kahiMea kālailai XRF, e loaʻa iā ʻoe ka noʻonoʻo maopopo e kiʻi i nā metala kūpono āu e pono ai.
