ʻO ke kūlana alumini no ka lumi kuhina / puka / pukaaniani a me ka mea hana pono hale

Māhele pinepine ʻia nā pā alumini i nā ʻano ʻelua aʻe:

1. Hoʻokaʻawale ʻia i loko o ka hoʻohui okaina.
Pā alumina maʻemaʻe kiʻekiʻe (ʻolokaʻa ʻia mai ka aluminika maʻemaʻe kiʻekiʻe me kahi ʻike o 99.9 a ʻoi paha)
Pā alumini maʻemaʻe (hana ʻia ke ʻano i ka alumini maʻemaʻe i ʻōwili ʻia)
ʻO ka pā alumini paʻa
ʻO ka pā alumini hui a i ʻole ka papa brazed (kahi kumu kūikawā papa aluminika i loaʻa ʻia ma o nā ʻano ʻano hana like ʻole)
ʻO ka pā alumini i hoʻopili ʻia me ka aluminika (ua hoʻopili ʻia kahi pā alumini lahilahi ma waho o ka pā alumini no nā hana kūikawā)

2. Mahele ʻia e ka mānoanoa: (anakahi mm)
Pepa alumini 0.15-2.0
Papa kuʻuna (pepa aluminika) 2.0-6.0
Pā Aluminium 6.0-25.0
Pā alumini 25-200 Pālahalaha mānoanoa 200 a ʻoi

He helehelena nani ko ka pepa alumina i uhi ʻia me nā kala a me ka kūpaʻa kūpale lōʻihi. Maʻalahi ke hoʻouka i kona ikaika, a maikaʻi loa ke kūpaʻa ahi a me ka mālama ʻana i ka wela. Hoʻohui ʻia, maikaʻi loa ka hana ʻana o ka pepa aluminika i uhi ʻia i ke kala ma muli o ka kikoʻī o kāna mea, a hiki ke ʻōlelo ʻia he waiwai nui.
ʻAʻole pono ka papa o ka pā alumina i uhi ʻia i ke kala i ka indentation maopopo, ka nalowale ʻana o ka uhi ʻana, a i ʻole ke komo pono ʻana i ka uhi, a ʻae ʻia nā nalu, nā ʻami, a me nā palapū. Maʻalahi loa kēia mau mea e ʻike. ʻO ka mea nui e nānā pono ʻoe i ka ʻokoʻa o ke kala o ka pepa aluminika i uhi ʻia i ke kala. Inā ʻaʻole ʻoe e nānā pono, ʻaʻole maʻalahi ka ʻike ʻana, akā e hoʻopili ia i ka hopena hoʻonaninani hope loa i ka wā o ka noi.
