Daim hlau Cupronickel yog ib hom hlau tooj liab uas muaj nickel ua lub ntsiab alloying. Cov hlau tooj liab-nickel uas ua los ntawm cov hlau tooj liab-nickel nrog cov ntsiab lus thib peb xws li zinc, manganese, txhuas, thiab lwm yam hu ua zinc-nickel-nickel strips, manganese-nickel-nickel strips, thiab aluminium-nickel-nickel strips raws li qhov ntawd. Cov hlau tooj liab-nickel muaj kev tiv thaiv corrosion zoo, lub zog nruab nrab, plasticity siab, thiab tuaj yeem ua tiav los ntawm kev kub thiab txias siab.
Cov kab tooj dawb tau muab faib ua tsib pawg: cov kab tooj dawb ib txwm muaj, cov kab hlau dawb tooj, cov kab hlau dawb manganese, cov kab hlau dawb zinc thiab cov kab hlau dawb txhuas
Cov hlau tooj liab dawb feem ntau muaj plaub qib hlau xws li B0.6, B5, B19, thiab B30. Cov feem ntau siv yog B19 thiab B30, thiab muaj ntau qib hauv American standard series. Cov hlau tooj liab dawb yog cov khoom khov kho uas tsim los ntawm Cu thiab Ni, nrog lub ntsej muag-centered cubic lattice, raws li pom hauv Daim Duab 1-18. Thaum qhov kub qis dua 322 degrees, daim duab tooj liab-nickel theem muaj thaj chaw kub sib txawv ntawm metastable decomposition, ntxiv cov ntsiab lus thib peb xws li Fe, Cr, Sn, Ti, Co, Si, Al rau Cu-Ni alloy Etc., tuaj yeem hloov cov khoom sib xyaw, qhov kub thiab qhov chaw ntawm metastable decomposition, thiab tseem tuaj yeem txhim kho qee yam khoom ntawm cov hlau. Cov hlau tooj liab dawb muaj kev ua haujlwm txias thiab kub zoo. Nws tuaj yeem ua tiav zoo rau hauv ntau yam duab xws li phaj, strips, raj, rods, duab, thiab xov hlau. Kev ua haujlwm vuam zoo, tuaj yeem siv rau kev sib tsoo mos thiab tawv, roj shielded arc vuam thiab tsis kam vuam, thiab lwm yam. Kev ua tau zoo ntawm kev txiav yog 20% ​​ntawm cov tooj dag txiav dawb HPb63-3. Cov phaj tooj liab dawb zoo tib yam muaj kev tiv thaiv corrosion zoo, lub zog nruab nrab, plasticity siab, tuaj yeem ua tiav los ntawm kev kub thiab txias siab, thiab cov khoom hluav taws xob zoo. Ntxiv nrog rau kev siv ua cov ntaub ntawv tsim kho, nws tseem yog ib qho tseem ceeb uas muaj kev tiv thaiv siab thiab thermocouple alloy.
