He aha ka ʻokoʻa ma waena o ke kila, ka alumini a me ka metala keleawe?

Pepa metalahoʻohana nui ʻia i ka ʻoihana hana a aia ʻekolu mau ʻano mea metala nui: kila, aluminika a me ke keleawe.ʻOiai hāʻawi lākou āpau i kahi mea paʻa paʻa no ka hana ʻana i nā huahana, aia kekahi mau nuances kaulana e pili ana i nā waiwai kino.No laila, he aha nā ʻokoʻa ma waena o ke kila, ka alumini a me ka metala keleawe?

 

Nā waiwai pā kila

ʻO ka hapa nui o nā pā kila i hana ʻia me ke kila kila, aia ka chromium e pale ai i ka corrosion.ʻO ka pā kila he malleable a hiki ke hoʻololi a hanaʻia me ka maʻalahi.

ʻO ke kila ke ʻano maʻamau o ka metala, ʻo ka hapa nui o nā metala i hana ʻia ma ka honua holoʻokoʻa he kila, ma muli o kona kaulana kaulana ʻole, ua lilo ka pā kila i like like me ka sheet metal.

Aia nā papa kila i kēia mau māka:

304 kila kila

316 kila kila

410 kila kila

430 kila kila

 

ʻO ka hana o ka pā alumini

ʻOi aku ka māmā o ka pepa alumini ma mua o ke kila, a ma waho aʻe o ka māmā, hāʻawi pū kekahi metala alumini i kahi kiʻekiʻe o ka pale ʻana i ka corrosion.Hoʻohana maʻamau ia i nā kūlana kahi e pono ai ka makū, e like me ka hana ʻana o nā moku.Eia nō naʻe, pono e hoʻomaopopo ʻia ʻo ka alumini ka mea ʻino, akā ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o ka nui o nā ʻano metala ʻē aʻe.

Loaʻa i nā papa alumini nā māka penei:

Aluminum 1100-H14

3003-H14 alumini

5052-H32 alumini

6061-T6 Aluminum

 

Na waiwai o ke keleawepepa metala

ʻO ke keleawe ka mea i hoʻohui ʻia o ke keleawe a me kahi mea liʻiliʻi o ka zinc ikaika, kūpaʻa i ka corrosion a maikaʻi hoʻi ka conductivity uila.Ma muli o kāna mau waiwai conductive, hiki ke hoʻohana ʻia ka metala keleawe i nā noi uila kahi i koho maikaʻi ʻole ai ke kila a me ka alumini.

ʻO ke kila, ka aluminika a me ka metala keleawe he mea ikaika loa a hāʻawi i kahi kiʻekiʻe o ka pale ʻana i ka corrosion.ʻO ke kila ka mea ikaika loa, ʻo ka alumini ka māmā, a ʻo ke keleawe ka mea hoʻokele maikaʻi loa o nā metala ʻekolu.
