Pāpaʻi keleawe nikeli / pā keleawe keʻokeʻo

Ke keleawe keʻokeʻo maʻamau

ʻO ke keleawe keʻokeʻo he mea hoʻohui keleawe me ka nickel ka mea hoʻohui nui. He keʻokeʻo kālā a he ʻulaʻula metala, no laila ua kapa ʻia ʻo ia he keleawe keʻokeʻo. Ke hoʻoheheʻe ʻia ka nickel i ke keleawe ʻulaʻula a ʻoi aku ka ʻike ma mua o 16%, e like me ke keʻokeʻo ke kala o ka mea i loaʻa. ʻO ke kiʻekiʻe o ka nickel content, ʻoi aku ka keʻokeʻo o ke kala. ʻO ka nui o ka nickel i loko o ke keleawe keʻokeʻo he 25%.

Hiki i ke keleawe maʻemaʻe a me ka nickel ke hoʻomaikaʻi maikaʻi i ka ikaika, ka pale ʻana i ka corrosion, ka paʻakikī, ka pale uila a me nā waiwai pyroelectric, a hoʻemi i ka coefficient mahana o ka resistivity. No laila, ke hoʻohālikelike ʻia me nā ʻāpana keleawe ʻē aʻe, ʻoi aku ka maikaʻi o ka cupronickel i ka mechanical a me ke kino, ka ductility maikaʻi, ka paʻakikī kiʻekiʻe, ka waihoʻoluʻu nani, ka pale ʻana i ka corrosion, a me nā waiwai kiʻi hohonu. Hoʻohana nui ʻia ia i ka hana moku, petrochemical, nā mea uila, nā mea kani, nā mea lapaʻau, nā mea e pono ai i kēlā me kēia lā, nā mea hana lima a me nā māla ʻē aʻe, a he mea koʻikoʻi ke kūpaʻa a me ka thermocouple alloy. ʻO ka hemahema o ka cupronickel ʻo ia ka mea nui i hoʻohui ʻia-nickel he mea hoʻolālā liʻiliʻi a he kumu kūʻai.
