6J13 Manganin Alloy Sawb

Txheej Txheem Cej Luam Khoom

6J13 manganin hlau strip, ib yam khoom siv ua kom muaj zog siab uas tsim thiab tsim los ntawm Tankii Alloy Material, yog ib hom tooj liab-manganese-nickel (Cu-Mn-Ni) raws li cov khoom siv ua kom muaj zog. Ua los ntawm kev siv lub tshuab nqus tsev siab heev, ntau txoj kev txias dov, thiab cov txheej txheem tswj hwm huab cua annealing, cov kab no ua tiav qhov kev kam rau siab heev thiab cov khoom siv hluav taws xob sib xws. Nws koom ua ke cov txiaj ntsig tseem ceeb ntawm cov hlau manganin:ruaj khov siab resistivity, tsis tshua muaj kev tiv thaiv kub coefficient (TCR), thiabkev tiv thaiv corrosion zoo heev—ua rau nws yog cov khoom siv zoo tshaj plaws rau cov resistors ruaj khov, precision current shunts, thiab cov khoom siv ntsuas hluav taws xob hauv kev lag luam industrial instrumentation, automotive electronics, thiab precision equipment fields.

Cov Qauv Txheem & Lub Hauv Paus Khoom Siv

Cov Txiaj Ntsig Tseem Ceeb (piv rau Cov Khoom Siv Tiv Thaiv Ib Txwm Muaj)

Daim ntawv qhia txog 6J13 manganin sawv tawm rau nws qhov kev ua tau zoo thiab kev ua haujlwm tau zoo:

Qhov tsis kam tiv taus tau ruaj khov ntawm 0.44 ± 0.04 μΩ·m (20 ℃), thiab qhov nruab nrab ntawm qhov kub thiab txias tsis kam (TCR) yog txij li -20 × 10⁻⁶ / ℃ txog + 20 × 10⁻⁶ / ℃ hauv -50 ℃ txog 150 ℃, uas qis dua li ntawm constantan (6J40: ± 40 × 10⁻⁶ / ℃). Tom qab 1000 teev ua haujlwm ntawm 120 ℃, qhov kev hloov pauv tsis kam yog tsawg dua 0.01%, ua kom ntseeg tau tias qhov ntsuas ntev ntawm cov cuab yeej raug.

Cov hlau alloy lub microstructure sib xws (qhov loj ntawm cov noob ≤25μm) ua rau muaj kev ua haujlwm txias zoo heev. Hauv qhov kub ib nrab, nws lub zog tensile ncav cuag 550-650 MPa, thiab elongation yog 15-20%, uas tuaj yeem tiv taus qhov siab precision stamping thiab bending (yam tsawg kawg nkaus bending radius ≥2 × thickness) yam tsis muaj cracking. Lub ci ntsa iab annealed nto (Ra ≤0.2μm) yog tsim rau ultra-fine tshuaj etching, nrog qhov tsawg kawg nkaus etched kab dav ntawm 0.03 hli.

Lub Cu-Mn-Ni alloy system tsim ib daim zaj duab xis passive, uas tuaj yeem tiv taus qhov corrosion hauv huab cua, dej qab zib, thiab cov tshuaj lom neeg me me (pH 4-10). Nws dhau 1000-teev ASTM B117 ntsev tsuag sim tsis muaj xeb pom tseeb. Lub caij no, nws muaj qhov kub thiab txias qis (≤2μV / ℃ vs. tooj liab), zoo txo ​​qhov kev cuam tshuam ntawm kev ntsuas hauv cov voj voog qis-voltage.

Piv nrog rau 6J12 manganin alloy (resistivity 0.47 ± 0.03 μΩ·m), 6J13 muaj resistivity qis dua me ntsis tab sis ruaj khov dua thiab tus nqi tsim khoom qis dua. Nws yog qhov kev xaiv pheej yig rau cov khoom tiv taus qhov nruab nrab mus rau siab, sib npaug kev ua tau zoo thiab kev txuag nyiaj.
