Ko te 6J12, e mōhiotia ana ko te Manganin whakarerekētia, he koranu ātete-konupora-nikora tino tika.
Kua whakapūmautia i raro i te paerewa ā-motu o Haina GB/T 15018-1994, i hangaia mō ngā tono e hiahia ana ki ngā uara ātete tino pumau me te iti o te paheketanga pāmahana.
Ngā kaupapa matua:
Tauwehenga pāmahana ātete tino iti (TCR)
l EMF wera iti ki te parahi
He tino pai te pumau mo te wa roa
He pai te ngāwari mō te tuhi waea pai
He pai mō ngā pūnaha ine me te whakahaere tino tika
Te Hanga: Te Whānautanga o Manganin (1892)
Te pūtake o6J12E hoki ana ki te hanganga o Manganin e te kaipūtaiao Piritana a Edward Weston i te tau 1892.
1887: I hangaia e Weston a Constantan, te koranu ātete-iti-TCR tuatahi.
1892: I whakawhanakehia te Manganin mā te whakamahi i te tātai o Cu86%, Mn12%, Ni2%.
Te putanga matua: Tata ki te kore TCR tata ki te pāmahana rūma, kia mau ai te ātete.
1901–1990: Ko ngā ātete Manganin te paerewa ture mō te ohm i te Hononga o Amerika.
Nā tēnei mea hou i whakatakoto te turanga mō ngā rauemi ātete tika katoa o ēnei rā.
Te Whanaketanga: Mai i te Manganin ki te 6J12
Ko te 6J12 te putanga Hainamana kua whakapai ake, kua paerewahia hoki o te Manganin tuku iho, kua arotauhia mō ngā hiahia ahumahi o ēnei rā.
Ngā tau 1950: I tīmata a Haina i ngā mahi rangahau me te whakawhanake motuhake me te hanga i ngā koranu tino tika i te rohe hei whakakore i te whakawhirinaki ki ngā kawemai.
1994: I whakaputa a Haina i te GB/T 15018-1994, ā, i tapaina mana te koranu kua arotauhia ko 6J12.
Ngā Whakapainga: I tāpirihia te Si me te Fe iti hei whakarei ake i te ātete wera me te mahi tukatuka.
Painga: He pumau ake i roto i ngā taiao pāmahana teitei, haumākū teitei me ngā taiao ahumahi uaua.
6J12 Hanganga Paerewa
| Huānga | Ihirangi (%) | Mahi Matua |
| Parahi (Cu) | 84.0–86.0 | Rauemi turanga, e whakarato ana i te kawe hiko taketake me te pakari ā-mīhini |
| Manganēhi (Mn) | 11.0–13.0 | Ka whakanui ake i te ātete, ka whakaiti hoki i te TCR kia mau ai te pumau o te ātete |
| Nikara (Ni) | 1.0–3.0 | Ka whakau i te uara ātete, ka whakapai ake i te ātete waikura |
| Si, Fe | Aroturuki | Ka whakarei ake i te ātete wera me te ngāwari o te kukume waea mō te hanga papatipu |
Ngā Āhuatanga Matua o te Koranu 6J12
Ngā Āhuatanga Hiko
Ātete (20°C): 0.45–0.48 μΩ·m
TCR: ≤±10×10⁻⁶/℃ (−60°C ki te +60°C)
l EMF Wera vs. Cu: ≤1 μV/℃, e whakaiti ana i ngā hapa ine

He aha i whakawhanakehia ai te 6J12
He iti noa iho ngā herenga o te Manganin tuku iho i roto i te pumau tukatuka me te mahi pāmahana teitei, kāore i taea te whakatutuki i ngā whakaritenga ahumahi o ēnei rā.
I whakawhanakehia te 6J12 hei whakaoti i ēnei raruraru:
Ka whakaiti i te ātete i roto i ngā pāmahana rerekē, kia tika ai te ine
Ka whakapai ake i te roa o te ratonga i roto i ngā taiao ahumahi me te rererangi kino
l Whakarei ake i te mahi kukume waea kia urutau ki te whakaputa papatipu o ngā waea tino tika
