He koranu parahi-manganese-nickel (koranu CuMnNi) te waea manganānin hei whakamahi i te pāmahana rūma. He iti rawa te kaha hiko wera (emf) o te koranu ki te whakataurite ki te parahi.
Ko te waea manganine te mea e whakamahia ana mō te hanga i ngā paerewa ātete, ngā ātete waea tino tika, ngā potentiometers,whakawhitime ētahi atu taputapu hiko mengā wāhanga hiko.

Ngā Whakatakotoranga
Waea manganin/CuMn12Ni2 Waea e whakamahia ana i roto i ngā rheostat, ngā ātete, ngā shunt me ētahi atu waea manganin 0.08mm ki te 10mm 6J13, 6J12, 6J11 6J8
Ko te waea manganānin (waea cupro-manganese) he ingoa hokohoko mō te koranu he 86% te parahi, 12% te manganānin, me te 2-5% te nikara.
E whakamahia ana te waea me te pepa konukōre manganine i roto i te hanga ātete, inā koa ngā shunt ammeter, nā te mea he iti noa te pāmahana e whai hua ana ki te uara o te ātete me te pumau mō te wā roa.

Te Whakamahinga o te Manganin

E whakamahia ana te pepa konumohe me te waea hei hanga i te ātete, inā koa te shunt ammeter, nā te mea he tata kore te pāmahana o te ātete me te pumau mō te wā roa.
He whānuitia te whakamahinga o te koranu whakamahana ātete iti i ahu mai i te parahi i roto i ngā kaiwawao hiko ngaohiko iti, te whakawhiti wera nui, me ētahi atu hua hiko ngaohiko iti. Ko tētahi o ngā rauemi matua o ngā hua hiko ngaohiko iti. Ko ngā āhuatanga o ngā rauemi i hangaia e tā mātou kamupene ko te pumau ātete pai me te pumau teitei. Ka taea e mātou te tuku i ngā momo waea porowhita katoa, ngā rauemi papatahi me ngā rauemi pepa.
