Kiʻi kikoʻī

He aha ka ʻokoʻa ma waena o Copper, Brass, Bronze?

ʻO Copper, Brass a me Bronze, i kapa ʻia ʻo "Metala ʻulaʻula", hiki ke ʻano like i ka wā mua.Akā he nui nā ʻokoʻa o lākou i ka element, ka hana a pēlā aku.

keleawe

Hoʻohana ʻia ke keleawe ma nā ʻano huahana he nui ma muli o kāna conductivity uila a me ka thermal conductivity, ikaika maikaʻi, formability maikaʻi a me ke kūpaʻa ʻana i ka corrosion.Hana ʻia nā paipu a me nā paipu mai kēia mau metala ma muli o ko lākou kūpaʻa ʻana.Hiki iā lākou ke kūʻai maʻalahi a hoʻopaʻa ʻia, a nui nā mea hiki ke welded e nā ʻano kinoea, arc a me nā ʻano kūʻē.Hiki iā lākou ke hoʻomaʻamaʻa ʻia a hoʻomāliʻi ʻia e like me ke ʻano a me ka luster makemake ʻia.

Aia nā māka o ka Copper unalloyed, a hiki ke hoʻololi i ka nui o nā haumia i loko.Hoʻohana kūikawā ʻia nā māka keleawe ʻole o ka oxygen i nā hana kahi e pono ai ka conductivity kiʻekiʻe a me ka ductility.

ʻO kekahi o nā waiwai koʻikoʻi o ke keleawe kona hiki ke hakakā i ka bacteria.Ma hope o ka hoʻāʻo nui ʻana i ka antimicrobial e ka Environment Protection Agency, ua ʻike ʻia he 355 mau keleawe keleawe, me nā keleawe he nui, ua ʻike ʻia e pepehi i ka 99.9% o ka bacteria i loko o ʻelua mau hola o ka hoʻopili ʻana.ʻAʻole i hōʻino ʻia ka maikaʻi o ka antimicrobial.

Nā noi keleawe

ʻO ke keleawe kekahi o nā metala mua loa i ʻike ʻia.Ua hana nā Helene a me nā Roma i mea hana a i ʻole nā mea hoʻonani, a aia kekahi mau kikoʻī mōʻaukala e hōʻike ana i ka hoʻohana ʻana o ke keleawe e hoʻomaʻemaʻe i nā ʻeha a hoʻomaʻemaʻe i ka wai inu.I kēia mau lā, ʻike pinepine ʻia i nā mea uila e like me ka uwila ma muli o kona hiki ke hoʻokele pono i ka uila.

keleawe

ʻO ka keleawe ka mea nui i hui pū ʻia me ke keleawe me ka zinc i hoʻohui ʻia.Hiki i nā keleawe ke hoʻohui i ka nui o ka zinc a i ʻole nā mea ʻē aʻe.Hoʻopuka kēia mau hui ʻokoʻa i nā ʻano waiwai a me nā ʻano like ʻole o ke kala.ʻO ka nui o ka zinc e hāʻawi i ka mea i hoʻomaikaʻi i ka ikaika a me ka ductility.Hiki i ke keleawe ke kala mai ka ʻulaʻula a i ka melemele ma muli o ka nui o ka zinc i hoʻohui ʻia i ka alloy.

Inā he 32% a hiki i ka 39% ka nui o ka zinc o ke keleawe, e hoʻonui ʻia ka hana wela akā e kaupalena ʻia ka hana anu.

Inā loaʻa i ka keleawe ma luna o 39% zinc (laʻana - Muntz Metal), e loaʻa iā ia ka ikaika kiʻekiʻe a me ka ductility haʻahaʻa (ma ka lumi wela).

Noi keleawe

Hoʻohana mau ʻia ke keleawe no nā mea hoʻonaninani ma muli o kona ʻano like me ke gula.Hoʻohana maʻamau ia e hana i nā mea kani ma muli o kāna hana kiʻekiʻe a paʻa.

keleawe

ʻO Bronze kahi huila e komo nui ʻia me ke keleawe me ka hoʻohui ʻana i nā mea ʻē aʻe.I ka hapanui o nā hihia, ʻo ka mea hoʻohui i hoʻohui ʻia he tin, akā hiki ke hoʻohana ʻia ka arsenic, phosphorus, aluminika, manganese, a me ke silika e hana i nā waiwai like ʻole o ka mea.ʻO kēia mau mea a pau e hana i kahi huila ʻoi aku ka paʻakikī ma mua o ke keleawe wale nō.

Hōʻike ʻia ka Bronze e kona waihoʻoluʻu ʻulaʻula.Hiki iā ʻoe ke ʻike i ka ʻokoʻa ma waena o ke keleawe a me ke keleawe no ka mea he mau apo palupalu ke keleawe ma kona ʻili.

Nā noi keleawe

Hoʻohana ʻia ʻo Bronze i ke kūkulu ʻana i nā kiʻi kiʻi, nā mea kani a me nā mekala, a ma nā ʻoihana ʻoihana e like me nā bushings a me nā bearings, kahi maikaʻi o kāna metala haʻahaʻa ma ka friction metala.Loaʻa ka Bronze i nā noi nautical ma muli o kona kū'ē i ka corrosion.
