ʻO nā ʻano like ʻole o nā mea hoʻohuihui keleawe kiʻekiʻe a me ka Nickel haʻahaʻa me ke kū'ē kiʻekiʻe a haʻahaʻa paha e kaulana no ke koina wela haʻahaʻa o ke kū'ē. Loaʻa i kēia mau mea hoʻohuihui ke kū'ē kiʻekiʻe i ka oxidation a me ka corrosion kemika, hoʻohana ʻia kēia mau mea hoʻohuihui no nā resistors precision wire-wound, potentiometers, nā mea hoʻomalu leo, nā rheostats ʻoihana kaumaha a me nā kū'ē o ka motika uila. Hoʻohana ʻia nā ʻano like ʻole no ka hoʻomehana ʻana i nā kaula me nā mahana conductor haʻahaʻa a ma ke ʻano he wili paipu i loko o nā "fittings wili uila".Mea hoʻohuihui keleawe manganesehoʻohana ʻia he mea maʻamau no nā pale pale pololei, maʻamau a me shunt.
