ʻIkepili keleawe
| Nā hiʻohiʻona | ʻIke |
| Nā ʻano haʻahaʻa | 101, 110 |
| Kaʻina hana | ʻO ka mīkini CNC, ka hana ʻana i ka metala |
| Hoʻomanawanui | ISO 2768 |
| Nā noi | ʻO nā kaʻa kaʻa kaʻa, nā kīʻaha, nā mea hoʻopili uwea, a me nā mea uila ʻē aʻe |
| Nā koho hoʻopau | Loaʻa ʻia e like me ka mīkini, media blasted, a i ʻole lima-polled |
Loaʻa nā Subtypes Copper
| Haʻihaʻi | Ikaika U'i | Elongation ma ka Haka | ʻoʻoleʻa | ʻO ka mānoanoa | Temp |
| 110 Ke keleawe | 42,000 psi (1/2 paʻakikī) | 20% | ʻO Rockwell F40 | 0.322 paona / cu. i loko. | 500° F |
| 101 Ke keleawe | 37,000 psi (1/2 paʻakikī) | 14% | ʻO Rockwell F60 | 0.323 paona / cu. i loko. | 500° F |
ʻIke Nui no ke keleawe
ʻO nā ʻāpana keleawe a pau e pale i ka ʻino ʻia e ka wai hou a me ka mahu. I ka hapanui o nā kua'āina, moana a me nā ʻenehana ʻenehana, ʻoi aku ka pale ʻana o nā alloy keleawe i ka corrosion. Kūpaʻa ke keleawe i nā hoʻonā paʻakai, nā lepo, nā minela non-oxidizing, nā ʻakika organik a me nā hopena caustic. ʻO ka amonia mākū, nā halogens, nā sulphides, nā hoʻonā i loaʻa nā ion ammonia a me nā waikawa oxidizing, e like me ka waikawa nitric, e hoʻouka i ke keleawe. ʻAʻole maikaʻi ke kūʻē ʻana o nā ʻāpana keleawe i nā ʻakika inorganic.
ʻO ka pale ʻana o ka corrosion o nā ʻāpana keleawe mai ka hoʻokumu ʻana i nā kiʻiʻoniʻoni pili i ka ʻili. ʻO kēia mau kiʻiʻoniʻoni ʻaʻole hiki ke hoʻopōʻino ʻia no laila e pale ana i ka metala kumu mai ka hoʻouka hou ʻana.
ʻO nā ʻāpana nickel keleawe, keleawe aluminika, a me nā keleawe alumini e hōʻike ana i ke kūpaʻa maikaʻi loa i ka ʻino wai paʻakai.
Hoʻolima Uila
ʻO ka conductivity uila o ke keleawe ka lua ma mua o ke kālā. ʻO ka conductivity o ke keleawe he 97% o ka conductivity o ke kālā. Ma muli o kāna kumu kūʻai haʻahaʻa a me ka nui o ka nui, ʻo Copper ka mea maʻamau i hoʻohana ʻia no nā noi uila.
Eia nō naʻe, ʻo ka noʻonoʻo ʻana i ke kaumaha, ʻo ka hapa nui o nā laina mana uila kiʻekiʻe e hoʻohana i ka alumini ma mua o ke keleawe. Ma ke kaumaha, ʻo ka conductivity o ka alumini ma kahi o ʻelua o ke keleawe. He haʻahaʻa ka ikaika o nā alumini alumini i hoʻohana ʻia a pono e hoʻoikaika ʻia me ke kaula kila kiʻekiʻe tensile kiʻekiʻe i hoʻopaʻa ʻia me ka galvanized a i ʻole alumini i kēlā me kēia kaula.
ʻOiai ʻo ka hoʻohui ʻana o nā mea ʻē aʻe e hoʻomaikaʻi i nā waiwai e like me ka ikaika, e nalowale kekahi i ka conductivity uila. ʻO kahi laʻana he 1% hoʻohui o ka cadmium hiki ke hoʻonui i ka ikaika ma 50%. Eia naʻe, e hopena kēia i ka emi ʻana o ka conductivity uila o 15%.
