  • Npib Tsib Xee-Chromium Alloys

    Cov no yog tus cwj pwm los ntawm lawv lub siab tsis kam mus rau xeb ntawm ob qho tib si thiab siab kub (tsis kam mus rau qhov ntsuas), zoo siab-kub lub zog thiab hluav taws xob tsis kam. Muaj peb pawg loj ntawm cov alloys:

    • Ni-Cr (thiab tseem Ni-Cr-Fe) alloys nrog hluav taws xob tsis kam rau cov cua sov, xws li 70-30 (UNS N06008) thiab C-Qib (UNS N06004)

    • Ni-Cr alloys (nrog Fe thiab lwm cov alloying ntsiab) nrog zoo corrosion tsis kam. Cov paub zoo tshaj plaws yog Alloy 600 (UNS N06600) thiab Alloy 601 (UNS N06601)

    • Ni-Cr alloys nrog qhov kub-siab zog thiab nkag kuj, feem ntau muaj hnub nyoog-tawv, xws li Alloy X-750 (UNS N07750)

  • Nickel-Chromium-Hlau Alloys

    Muaj ob pawg ntawm alloys:

    • Ni - Cr - Fe alloys nrog lub zog zoo ntawm kub thiab muaj peev xwm tiv taus oxidation, carburisation thiab lwm yam kev kub siab tiv thaiv. Qhov zoo tshaj plaws-paub yog alloy 800 (UNS N08800) thiab nws cov hloov pauv 800H (UNS N08810) thiab 800HT (UNS N08811). (Tsis ntev los no, cov alloys tau muab cais ua cov hlau stainless ntawm lawv cov qib Fe cov ntsiab lus)

    • Ni - Cr - Fe (nrog Mo thiab Cu) alloys nrog zoo heev corrosion tsis kam hauv cov ntawv thov tshwj xeeb. Tej zaum qhov zoo tshaj plaws-paub yog alloy 825 (UNS N08825), uas muaj qhov tshwj xeeb tsis kam rau sulfuric acid. Alloy G-3 (UNS N06985) muaj qhov tshwj xeeb corrosion tsis kam rau cov lag luam phosphoric acids zoo li ntau lub ntsiab kev daws teeb meem muaj feem ntau oxidizing acids.

  • Nickel-Chromium-Molybdenum Alloys

    Cov no muaj kev tiv thaiv tiv thaiv corrosion, ntawm uas Alloy C-276 (N10276) yog qhov zoo tshaj plaws-paub. Lawv muaj qhov tshwj xeeb tiv thaiv kom txo cov acids xws li hydrochloric thiab sulfuric. Muaj ntau ntau cov qauv hloov raws li cov lus sib xyaw no, uas tau hloov kho qib Cr thiab Mo thiab, qee qhov xwm txheej, ntxiv rau Cu lossis W txhawm rau txhawm rau txhawm rau txhim kho qhov tsis kam tiv thaiv cov kev mob uas yog ntau dua oxidising lossis txo qis dua. Cov no suav nrog Alloy C-22 (N06022), Alloy 59 (N08059), Alloy C-2000 (UNS N06200), thiab Alloy 686 (N06686).

  • Nickel-Chromium-Cobalt Alloys

    Qhov sib ntxiv ntawm cobalt thiab molybdenum imparts cov khoom ua tau-txhim kho kom ruaj khov thiab muaj qhov siab ntawm cov menyuam nkag sib zog rau ntau qhov 617 (UNS N06617).

  • Npib Tsib Xee-Titanium Alloys

    55% npib tsib xee-titanium alloy (UNS N01555) (tseem hu ua Nitinol) muaj cov khoom nco-zoo. Thaum tsim nyob rau ntawm ib qho kub thiab tom qab ntawd deformed ntawm qis dua, nws rov qab nws daim ntawv qub thaum rov kho. Cov kev hloov pauv tuaj yeem hloov kho los ntawm kev tswj kom ceev faj ntawm kev sib xyaw. Cov cuab yeej siv kho mob thiab cov xaim hluav taws xob tshwj xeeb yog ob yam ntawm kev siv. Cov qub ntau yam kuj tuaj yeem yauv los ua ke ntawm kev deformation thiab tseem rov qab mus rau nws qhov qub (cov cuab yeej super-elastic). Cov cuab yeej no tau raug coj los siv rau cov ntawv thov muaj ntau haiv neeg raws li qhov pom cov duab kos thiab cov duab hluav taws xob uas ua rau muaj qhov av qeeg nyob hauv cov tuam tsev pob zeb.
