Cupronickel CuNi44 copper-nickel alloy resistance wire with medium-low resistivity
ʻO kēia huila keleawe-nickel kūpaʻa, i ʻike ʻia ʻo Constantan, ua ʻike ʻia e ke kūpaʻa uila kiʻekiʻe i hui pū ʻia me kahi koena wela liʻiliʻi o ke kūpaʻa. Hōʻike pū kēia alloy i ka ikaika tensile kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion. Hiki ke hoʻohana ʻia ma nā mahana a hiki i 600°C i ka lewa.
ʻO CuNi44 kahi hui keleawe-nickel (CuNi alloy) mekūʻokoʻa haʻahaʻa haʻahaʻano ka hoʻohana ʻana i nā mahana a hiki i 400°C (750°F).
Hoʻohana maʻamau ʻia ʻo CuNi44 no nā noi e like me nā kaula wela, fuses, shunt, resistors a me nā ʻano mea hoʻokele.
