6J12, yomwe imadziwikanso kuti Manganin yosinthidwa, ndi aloyi yolimba kwambiri yolimbana ndi mkuwa, manganese, nickel.
Ili ndi muyezo wofanana ndi muyezo wa dziko lonse wa GB/T 15018-1994 wa ku China, wopangidwira ntchito zomwe zimafuna mphamvu zokhazikika komanso kutentha kochepa.
Mfundo zazikulu:
l Choyezera kutentha chotsika kwambiri (TCR)
l Low kutentha EMF motsutsana ndi mkuwa
l Wabwino kwambiri kwa nthawi yayitali
l Wabwino ductility kwa chojambula cha waya wabwino
l Oyenera muyeso wolondola kwambiri komanso machitidwe olamulira
Kupangidwa: Kubadwa kwa Manganin (1892)
Chiyambi cha6J12Kubwerera m'mbuyo ku kupangidwa kwa Manganin ndi wasayansi waku Britain Edward Weston mu 1892.
l 1887: Weston adapanga Constantan, aloyi yoyamba yotsutsa ya TCR yochepa.
l 1892: Manganin idapangidwa ndi njira ya Cu86%, Mn12%, Ni2%.
l Kupambana kwapakati: TCR yoyandikira zero pafupi ndi kutentha kwa chipinda, kuonetsetsa kuti kukana kukhazikika.
l 1901–1990: Ma resistor a Manganin anali ngati muyezo wovomerezeka wa ohm ku United States.
Kupangidwa kumeneku kunakhazikitsa maziko a zipangizo zonse zamakono zotsukira molondola.
Kusintha: Kuchokera ku Manganin kupita ku 6J12
6J12 ndi mtundu wa Manganin wachikhalidwe wa ku China wokonzedwanso komanso wokhazikika, wokonzedwa bwino kuti ugwirizane ndi zosowa zamakono zamafakitale.
l 1950s: China inayamba kafukufuku wodziyimira pawokha komanso kuyika malo a alloys olondola kuti ithetse kudalira kwa zinthu zochokera kunja.
l 1994: China idatulutsa GB/T 15018-1994, ndikutchula mwalamulo alloy yokonzedwa bwino ya 6J12.
l Zosintha: Zinawonjezera trace Si ndi Fe kuti ziwonjezere kukana kutentha ndi magwiridwe antchito opangira.
l Ubwino: Kukhazikika bwino m'malo otentha kwambiri, chinyezi chambiri komanso malo ovuta a mafakitale.

| Chinthu | Zomwe zili mkati (%) | Ntchito Yaikulu |
| Mkuwa (Cu) | 84.0–86.0 | Zipangizo zoyambira, zimapereka mphamvu yoyendetsera zinthu komanso kulimba kwa makina |
| Manganese (Mn) | 11.0–13.0 | Zimawonjezera kukana kwa mankhwala ndikuchepetsa TCR kuti zitsimikizire kukhazikika kwa mankhwala |
| Nikeli (Ni) | 1.0–3.0 | Imalimbitsa mphamvu yotsutsa ndikuwonjezera kukana kwa okosijeni |
| Si, Fe | Kutsata | Zimathandizira kukana kutentha komanso kukopa waya kuti upange zinthu zambiri |
Katundu Wofunika Kwambiri wa 6J12 Alloy
Katundu Wamagetsi

l Mphamvu yokoka: 680–720 MPa
l Kutalika: 12–15%
l Kusungunuka bwino, koyenera kukoka waya woonda mpaka 0.05 mm
Chifukwa Chake 6J12 Inapangidwa
Manganin yachikhalidwe inali ndi zofooka pakukhazikika kwa ntchito yokonza ndi kutentha kwambiri, zomwe sizikanatha kukwaniritsa zofunikira zamafakitale amakono.
6J12 idapangidwa kuti ithetse mavuto awa:
l Amachepetsa kukana kugwedezeka kutentha kusinthasintha, kuonetsetsa kuti muyeso ndi wolondola
l Imawongolera moyo wautumiki m'malo ovuta a mafakitale ndi ndege
l Imawonjezera magwiridwe antchito a waya kuti igwirizane ndi kupanga mawaya olondola kwambiri
l Akwaniritsa miyezo yokhwima ya dziko lonse ya zida zamagetsi zolondola kwambiri
Kugwiritsa Ntchito Kwachizolowezi kwa Waya wa 6J12
Waya wathu wa 6J12 wolondola kwambiri umagwiritsidwa ntchito kwambiri m'magawo olondola kwambiri, zomwe zimapereka magwiridwe antchito odalirika pazinthu zofunika:
l Zoyeserera zoyeserera bwino komanso mabokosi otsutsa
l Ma shunt a zida zamagetsi, ma multimeter ndi ma power meter
l Zoyezera kupsinjika ndi masensa olondola kwambiri owongolera mafakitale
l Zida zamagetsi ndi zida zankhondo zomwe zili ndi zofunikira zodalirika kwambiri
l Zida zoyezera molondola komanso zida zoyezera zinthu
6J12 motsutsana ndi Manganin Yachikhalidwe

Ubwino wa 6J12 mu Makampani Amakono
l Cholowa Chotsimikizika: Zaka zoposa 130 za kusonkhanitsa kwaukadaulo kuchokera ku Manganin
l Ultra-khola ntchito: Kukana pang'ono kusuntha pakapita nthawi ndi kusintha kwa kutentha
l Strong processability: Yabwino kwambiri popanga mawaya olondola osiyanasiyana
Kutsatira Malamulo: Kukwaniritsa miyezo ya GB, ASTM, ndi IEC, yoyenera kugwiritsidwa ntchito padziko lonse lapansi
l Yotsika mtengo: Imayendetsa bwino magwiridwe antchito komanso kutsika mtengo kwa mafakitale
Mapeto
6J12 Precision Alloy ndi kusintha kwamakono kwa Manganin yakale, kuphatikiza zaka 130 za kupita patsogolo kwaukadaulo.
Kuyambira pamene idapangidwa mu 1892 mpaka pa zipangizo zamakono za dziko, siingasinthidwe ndi zipangizo zamagetsi zolondola kwambiri.
Waya wathu wa 6J12 walandira cholowa ichi, kupereka magwiridwe antchito odalirika komanso okhazikika pazida zolondola, masensa, ndi makina oyendetsa ndege padziko lonse lapansi. Ngati muli ndi zosowa zina zokhudzana ndi izi, chonde musazengereze kutero.Lumikizanani nafenthawi iliyonse.
