ONE-DʻokoʻaPnā kumu:
1. Ke kumu o ke keleawe: Hoʻohana pinepine ʻia ke keleawe i ka hana ʻana i nā kiwikā, nā paipu wai, nā paipu hoʻohui no nā ʻāpana ea hoʻoluʻu kūloko a me waho, a me nā radiators.
2. Ke kumu o ke keleawe tin: ʻO ke keleawe tin kahi metala hao ʻole me ka liʻiliʻi loa o ka hoʻoheheʻe ʻana, hoʻohana ʻia e hana i nā mea hoʻoheheʻe me nā ʻano paʻakikī, nā contours maopopo, a me nā koi paʻa ea haʻahaʻa. He kūpaʻa loa ke keleawe tin i ka pala i ka lewa, ka wai kai, ka wai maʻemaʻe, a me ka mahu, a hoʻohana nui ʻia i nā paila mahu a me nā ʻāpana moku.
3. Nā kumu o ke keleawe: hoʻohana nui ʻia no ka hana ʻana i nā lako uila e like me nā mīkini hana uila, nā kaʻa uila, nā kaula, nā mea hoʻololi uila, nā mea hoʻololi uila, a me nā lako hana hoʻoili wela e like me nā mea hoʻololi wela, nā paipu uila, a me nā mea hōʻiliʻili pālahalaha no nā mea hoʻomehana lā.
ʻELUA- Nā ʻano like ʻole:
1. Nā ʻano o ke keleawe: He kūpaʻa ikaika ko ke keleawe i ka ʻaʻahu ʻana.
2. Nā ʻano o ke keleawe tin: ʻO ka hoʻohui ʻana i ke kēpau i ke keleawe tin hiki ke hoʻomaikaʻi i kona hiki ke mīkini a me ke kūpaʻa ʻana i ka ʻaʻahu, ʻoiai ʻo ka hoʻohui ʻana i ka zinc hiki ke hoʻomaikaʻi i kāna hana hoʻolei. Loaʻa i kēia metala nā waiwai mechanical kiʻekiʻe, ka hana hōʻemi ʻaʻahu, a me ke kūpaʻa ʻana i ka pala, maʻalahi ka mīkini, loaʻa ka hana brazing a me ka hoʻopili maikaʻi ʻana, ka coefficient shrinkage haʻahaʻa, a ʻaʻole magnetic.
3. Nā ʻano o ke keleawe ʻulaʻula: he conductivity maikaʻi a me ka conductivity thermal, plasticity maikaʻi loa, a maʻalahi hoʻi e hana ʻia e ke kaomi wela a me ke kaomi anu.
ʻEkolu ʻano Kemika like ʻole:
1. ʻIkepili o ke Keleawe: ʻO ke keleawe kahi mea hoʻohuihui i hana ʻia me ke keleawe a me ka zinc. ʻO ke keleawe i hana ʻia me ke keleawe a me ka zinc ua kapa ʻia he keleawe maʻamau. Inā i hana ʻia me nā mea hoʻohuihui he nui o ʻelua a ʻoi aku paha mau mea, ua kapa ʻia ʻo ia he keleawe kūikawā.
2. ʻIke holoʻokoʻa o ke keleawe tin: Keleawe me ka tin ma ke ʻano he mea hoʻohuihui nui.
3. ʻIkepili o ke Keleawe ʻUlaʻula: ʻO ke keleawe ʻulaʻula, i ʻike ʻia hoʻi he keleawe ʻulaʻula, he mea maʻalahi ia o ke keleawe, i kapa ʻia ma muli o kona kala ʻulaʻula poni. Hiki ke loaʻa nā ʻano like ʻole i ke keleawe. He keleawe maʻemaʻe ʻoihana ke keleawe ʻulaʻula, me kahi kiko heheʻe o 1083 ℃, ʻaʻohe hoʻololi allosteric, a me kahi density pili o 8.9, ʻo ia ka ʻelima manawa o ka magnesium. ʻO ke kaumaha o ka nui like ma kahi o 15% ke kaumaha ma mua o ke kila maʻamau.
ʻEHĀ-ʻIke hou aku e pili ana i ke keleawe, ke keleawe, ke keleawe
He metala ʻulaʻula poni ke keleawe maʻemaʻe me kahi waihoʻoluʻu poni ma hope o ka hoʻokumu ʻia ʻana o kahi ʻili keleawe oxide ma luna o ka ʻili. No laila, ua kapa pinepine ʻia ke keleawe maʻemaʻe ʻoihana he keleawe poni a i ʻole ke keleawe electrolytic. ʻO ka density he 8-9g/cm3, a ʻo ke kiko heheʻe he 1083°C. He maikaʻi ka conductivity o ke keleawe maʻemaʻe a hoʻohana nui ʻia i ka hana ʻana i nā uea, nā kaula, nā pulumu, a pēlā aku; ʻO ka conductivity thermal maikaʻi, i hoʻohana pinepine ʻia e hana i nā mea hana magnetic a me nā mika e pono ai ka pale ʻana mai ka hoʻopilikia magnetic, e like me nā compasses a me nā mea hana mokulele; ʻO ka plasticity maikaʻi loa, maʻalahi ke kaomi wela a me ka hana kaomi anu, hiki ke hana ʻia i nā mea keleawe e like me nā paipu, nā kaola, nā uea, nā ʻāpana, nā papa, nā foil, a pēlā aku.
He mea hoʻohuihui keleawe a me ka zinc ke keleawe. ʻO ke keleawe maʻalahi loa he mea hoʻohuihui keleawe zinc binary, i ʻike ʻia ʻo ke keleawe maʻalahi a i ʻole ke keleawe maʻamau. ʻO ka hoʻololi ʻana i ka nui o ka zinc i loko o ke keleawe hiki ke loaʻa i ke keleawe me nā ʻano mechanical like ʻole. ʻO ke kiʻekiʻe o ka nui o ka zinc i loko o ke keleawe, ʻoi aku ka kiʻekiʻe o kona ikaika a me ka haʻahaʻa iki o kona plasticity. ʻAʻole ʻoi aku ka nui o ka zinc o ke keleawe i hoʻohana ʻia ma ka ʻoihana ma mua o 45%, a ʻo ke kiʻekiʻe o ka nui o ka zinc e alakaʻi ai i ka brittleness a me ka hōʻino ʻana o nā waiwai o ka mea hoʻohuihui.
ʻO Tin Bronze ka metala mua loa i hoʻohana ʻia ma ka mōʻaukala, i kapa mua ʻia he keleawe. Ua kapa ʻia ʻo ia he keleawe ma muli o kona kala hina polū. He kiʻekiʻe nā waiwai mechanical o ke keleawe Tin, kūpaʻa maikaʻi i ka palaho, hoʻēmi i ka friction, a me ka hana hoʻolei maikaʻi; haʻahaʻa ka ʻike i ka wela nui a me nā kinoea, hana kuʻi maikaʻi, ʻaʻohe ferromagnetism, a me ka coefficient shrinkage haʻahaʻa. ʻOi aku ka kiʻekiʻe o ke kūpaʻa ʻana o ke keleawe Tin ma mua o ke keleawe i ka lewa, ka wai kai, ka wai maʻemaʻe, a me ka mahu.
