6J13 Manganin Alloy Strip

Chidule cha Zamalonda

Mzere wa aloyi wa 6J13 wa manganin, chinthu chopangidwa ndi aloyi wolondola kwambiri wopangidwa payokha ndi Tankii Alloy Material, ndi aloyi wamba wokhazikika pa copper-manganese-nickel (Cu-Mn-Ni). Chopangidwa kudzera mu njira zapamwamba zosungunulira vacuum, multi-pass cold-rolling, komanso njira zowongolera mpweya, strip iyi imakwaniritsa kulekerera kolimba kwambiri komanso mphamvu zamagetsi zofanana. Imagwirizanitsa zabwino zazikulu za ma aloyi a manganin:kukana kwakukulu kokhazikika, choyezera kutentha kotsika (TCR)ndikukana dzimbiri kwabwino kwambiri— zomwe zimapangitsa kuti ikhale chinthu chomwe chimakonda kwambiri pa ma resistor okhazikika kwambiri, ma shunt amagetsi olondola, ndi zida zamagetsi zoyezera m'mafakitale, zamagetsi zamagalimoto, ndi zida zolondola.

Makhalidwe Okhazikika & Maziko Azinthu

Ubwino Waukulu (poyerekeza ndi Ma Alloys Otsutsana ndi Common)

Mzere wa manganin wa 6J13 umadziwika bwino chifukwa cha magwiridwe ake olondola komanso kuthekera kwake kukonzedwa bwino:

Kukana kumasungidwa bwino pa 0.44±0.04 μΩ·m (20℃), ndipo avareji ya resistance temperature coefficient (TCR) imayambira pa -20×10⁻⁶/℃ mpaka +20×10⁻⁶/℃ mkati mwa -50℃ mpaka 150℃, yomwe ndi yotsika kuposa ya constantan (6J40: ±40×10⁻⁶/℃). Pambuyo pa maola 1000 ogwirira ntchito pa 120℃, kukana kumakhala kochepera 0.01%, kuonetsetsa kuti zida zolondola zikuyezedwa bwino kwa nthawi yayitali.

Kapangidwe kake ka alloy (kukula kwa tirigu ≤25μm) kamathandiza kugwira ntchito bwino kwambiri kozizira. Pa kutentha kwa theka, mphamvu yake yolimba imafika 550-650 MPa, ndipo kutalika kwake ndi 15-20%, komwe kumatha kupirira kupondaponda kolondola kwambiri (ma radius ocheperako opindika ≥2× makulidwe) popanda kusweka. Malo owala opindika (Ra ≤0.2μm) ndi oyenera kupeta mankhwala ofewa kwambiri, okhala ndi mzere wocheperako wopindika wa 0.03mm.

Dongosolo la Cu-Mn-Ni alloy limapanga filimu yolimba yopanda mphamvu, yomwe imatha kupirira dzimbiri la mumlengalenga, madzi abwino, ndi malo ocheperako a mankhwala (pH 4-10). Imadutsa mayeso a ASTM B117 salt spray a maola 1000 popanda dzimbiri lodziwika bwino. Pakadali pano, ili ndi mphamvu yochepa ya thermoelectric (≤2μV/℃ poyerekeza ndi mkuwa), zomwe zimachepetsa bwino kusokonezedwa kwa muyeso m'mabwalo otsika amagetsi.

Poyerekeza ndi 6J12 manganin alloy (resistivity 0.47±0.03 μΩ·m ), 6J13 ili ndi resistivity yotsika pang'ono koma yokhazikika kwambiri komanso mtengo wotsika wopanga. Ndi chisankho chotsika mtengo cha zigawo zotsutsana pakati mpaka pamwamba, magwiridwe antchito komanso osawononga ndalama zambiri.

Mapulogalamu Odziwika

Tankii Alloy Material imagwiritsa ntchito njira zowongolera khalidwe la 6J13 manganin alloy strips: gulu lililonse limayesedwa ndi XRF chemical composition, mayeso a TCR olondola kwambiri (tester yolimbana ndi kutentha yolamulidwa ndi kulondola ±0.1 ppm/℃), kuyang'aniridwa ndi laser dimensional, ndi mayeso a kutentha kwa maola 1000. Zitsanzo zaulere (100mm × 100mm) ndi malipoti oyesera zinthu mwatsatanetsatane (MTR) amapezeka mukapempha. Gulu lathu laukadaulo limapereka chithandizo chokonzedwa bwino—kuphatikizapo kukonza magawo a etching ndi kusankha kutentha kwa njira zopondera—kuti lithandize makasitomala kukulitsa magwiridwe antchito a 6J13 mu ntchito zolondola.
