ʻO nā ʻano like ʻole o ke keleawe kiʻekiʻe a me ka haʻahaʻa Nickel content alloys me ke kūpaʻa kikoʻī kiʻekiʻe a haʻahaʻa paha he mea kaulana no ka coefficient wela haʻahaʻa o ke kūpaʻa. Loaʻa i ke kūpaʻa kiʻekiʻe i ka oxidation a me ka corrosion kemika, ua hoʻohana ʻia kēia mau mea hoʻohui no nā resistors precision wire-wound, potentiometers, nā mana hoʻomalu leo, wiliwili i nā rheostats hana kaumaha a me nā pale kaʻa uila. Hoʻohana ʻia nā ʻokoʻa like ʻole no ka hoʻomehana ʻana i nā kaula me nā haʻahaʻa conductor haʻahaʻa a ma ke ʻano he paipu hoʻoheheʻe ʻia i loko o "nā lako wili uila".Pākuʻi manganese keleawehoʻohana ʻia kahi mea maʻamau no ka precision, standard and shunt resistors.
