ʻO Copper nickel kahi hui keleawe-base me ka nickel ka mea hoʻohui nui. ʻO nā mea ʻelua i kaulana loa o nā ʻāpana waiwai keleawe he 10 a i ʻole 30% o ka nickel. Ma ka hoʻohui ʻana i ka manganese, hao, zinc, aluminika a me nā mea ʻē aʻe, lilo ia i mea paʻakikī keleawe nickel alloy no nā kumu kūikawā.
Loaʻa i ka Zinc Copper Nickel nā waiwai mechanical piha, maikaʻi ka corrosion resistance, ke anuanu maikaʻi a me ka hoʻoheheʻe ʻana i ka wela, ka ʻoki maʻalahi, hiki ke hana ʻia i uea, bar a me ka pā, hoʻohana ʻia no ka hana ʻana i nā mea kani, nā mika, nā mea lapaʻau, nā pono o kēlā me kēia lā a me nā kamaʻilio a me nā kula ʻē aʻe. o na mahele pololei.
