Whakaahuatanga Poto:

(I ētahi wā ka hē te tuhi ko Cupernickel) ko te Coppernickel rānei he koranu o te parahi, te nikara me ngā poke whakapakari, pērā i te rino me te manganese. Kāore te Cupronickel e waikura i roto i te wai moana, nā te mea ka whakatikatikaina tōna pūmanawa hiko kia noho koretake ki te wai moana. Nā tēnei ka whakamahia mō ngā taputapu moana, ā, i ētahi wā mō ngā poroporo, ngā toki porotaka me ngā anga o ngā poti tō utu nui, ngā poti hī ika me ētahi atu poti mahi.
He mea noa te whakamahi i roto i ngā moni hiriwa maha o ēnei rā. Ko te ranunga noa he 75% parahi, 25% nikara, me te iti o te manganese. I ngā wā o mua, i whakakorea ngā moni hiriwa tūturu ki te cupronickel. Ahakoa te nui o te parahi, ko te tae o te cupro-nickel he hiriwa.
E whakamahia ana i roto i ngā thermocouples, ā, e whakamahia ana he koranu parahi 55%/nikara 45% hei hanga ātete tino tika.
