ʻO Manganin kahi inoa hōʻailona no kahi metala o 86% keleawe, 12% manganese, a me 2% nickel. Ua hoʻomohala mua ʻia e Edward Weston i ka makahiki 1892, e hoʻomaikaʻi ana ma luna o kāna Constantan (1887).

He metala kū'ē me ke kū'ē kūpono a me ke ana wela haʻahaʻa. ʻAʻole palahalaha ke kiʻikuhi kū'ē/mahana e like me nā constantans a ʻaʻole hoʻi maikaʻi nā waiwai kū'ē i ka palaho.

Hoʻohana ʻia ka pepa kini a me ka uea Manganin i ka hana ʻana i nā resistors, ʻoiai ka ammeternā shunt, ma muli o kona ʻano wela ʻole o ka waiwai kū'ē[1] a me ke kūpaʻa lōʻihi. Ua lawelawe kekahi mau resistors Manganin ma ke ʻano he kūlana kānāwai no ka ohm ma ʻAmelika Hui Pū ʻIa mai 1901 a 1990.[2]Uea manganinhoʻohana ʻia hoʻi ma ke ʻano he mea alakaʻi uila i nā ʻōnaehana cryogenic, e hōʻemi ana i ka hoʻoili wela ma waena o nā wahi e pono ai nā pilina uila.

Hoʻohana ʻia ʻo Manganin i nā ana no nā haʻawina o nā nalu haʻalulu kiʻekiʻe (e like me nā mea i hana ʻia mai ka pahū ʻana o nā mea pahū) no ka mea he haʻahaʻa kona ʻike koʻikoʻi akā he kiʻekiʻe kona ʻike kaomi hydrostatic.
