6J12, inozivikanwawo seManganin yakagadziriswa, isimbi inorwisa mhangura-manganese-nickel yakasimba.
Yakagadzirwa pasi pemutemo wenyika weChina weGB/T 15018-1994, wakagadzirirwa mashandisirwo anoda simba rakasimba uye tembiricha shoma.
Zvinokosha:
l Ultra-low resistance tembiricha coefficient (TCR)
l Low thermal EMF inopesana nemhangura
l Kugadzikana kwenguva refu kwakanaka kwazvo
l Ductility yakanaka yekudhirowa waya yakanaka
l Yakakodzera kuyerwa kwakanyatsonaka uye masisitimu ekudzora
Kugadzirwa: Kuberekwa kweManganin (1892)
Kwakatangira6J12inodzokera shure kusvika pakugadzirwa kweManganin nemusayendisiti wekuBritain Edward Weston muna 1892.
l 1887: Weston akagadzira Constantan, alloy yekutanga yekudzivirira TCR yakaderera.
l 1892: Manganin yakagadzirwa nefomura yeCu86%, Mn12%, Ni2%.
l Kubudirira kwepakati: Near-zero TCR iri pedyo netembiricha yemukamuri, zvichiita kuti isarambe yakasimba.
l 1901–1990: Manganin resistors akashanda semutemo we ohm muUnited States.
Kugadzirwa uku kwakaisa hwaro hwezvinhu zvese zvemazuva ano zvinodzivirira kupenya.
Kushanduka-shanduka: Kubva kuManganin kusvika ku6J12
6J12 ndiyo vhezheni yeManganin yechinyakare yakagadziridzwa uye yakajairika yekuChina, yakagadzirirwa zvinodiwa zvemaindasitiri emazuva ano.
Kuma1950: China yakatanga R&D yakazvimirira uye kuiswa kwemhando dzealloys dzakanyatsogadzirwa kuti iparadze kuvimba nekutenga zvinhu kubva kunze kwenyika.
l 1994: China yakaburitsa GB/T 15018-1994, ichitumidza zviri pamutemo alloy yakagadziriswa 6J12.
Kuvandudzwa: Yakawedzera trace Si naFe kuti iwedzere kuramba kupisa uye mashandiro ekugadzirisa.
l Betsero: Kugadzikana kuri nani munzvimbo dzine tembiricha yakakwira, hunyoro hwakawanda uye dzakaoma dzemaindasitiri.

Chikonzero nei 6J12 Yakagadzirwa
Manganin yechinyakare yaive nemiganhu mukugadzikana kwekugadzirisa uye kushanda kwekupisa kwakanyanya, izvo zvaisakwanisa kusangana nezvinodiwa zvemaindasitiri emazuva ano.
6J12 yakagadzirwa kugadzirisa matambudziko aya:
l Inoderedza kuramba kudonha mukupisa kunochinja-chinja, ichivimbisa kuyera kwakarurama
l Inovandudza hupenyu hwebasa munzvimbo dzakaoma dzemaindasitiri nedzemuchadenga
l Inovandudza mashandiro ekudhirowa kwewaya kuti ienderane nekugadzirwa kwakawanda kwewaya dzakarurama
l Inosangana nemitemo yenyika yakaoma yezvikamu zvemagetsi zvakanyatsonaka
Maitiro Akajairika e6J12 Waya
Waya yedu ye6J12 chaiyo inoshandiswa zvakanyanya muminda ine kururama kwakanyanya, ichipa mashandiro akavimbika kune zvikamu zvakakosha:
l Zvigadziriso zvemhando yepamusoro uye mabhokisi ekudzivirira
l Zvishandiso zvemagetsi, multimeters uye power metres
l Mageji ekukwesha uye masensa akanyatsonaka ekudzora maindasitiri
l Aerospace nemauto zvemagetsi zvikamu zvine zvinodiwa zvakavimbika zvakanyanya

Mhedziso
6J12 Precision Alloy ndiyo shanduko yemazuva ano yeManganin yekare, ichibatanidza makore zana nemakumi matatu ekufambira mberi kwetekinoroji.
Kubva pakugadzirwa kwayo muna 1892 kusvika pakushandiswa kwezvinhu zvemazuva ano, haichatsiviwi nemidziyo yemagetsi ine hunyanzvi hwepamusoro.
Waya yedu ye6J12 inogara nhaka iyi, ichipa mashandiro akavimbika uye akagadzikana ezvishandiso zvakanyatsonaka, masensa, uye masisitimu emuchadenga pasi rese. Kana muine zvimwe zvinodiwa zvinoenderana nazvo, ndapota inzwa wakasununguka kutaura nesuchero nguva.
