    Khoom cim npe

    FeCrAl alloy (Iron-Chromium-Aluminium) yog qhov kub-kub kuj alloy muaj feem ntau ntawm hlau, chromium, thiab txhuas, nrog rau me me ntawm lwm yam xws li silicon thiab manganese. Cov alloys no tau siv dav hauv cov ntawv thov uas yuav tsum muaj kev tiv thaiv oxidation thiab kev ua haujlwm kub zoo, ua rau lawv zoo tagnrho rau kev siv hluav taws xob cua sov, cov khoom siv hluav taws xob, thiab cov ntawv siv kub xws li cua sov coils, radiant heaters, thiab thermocouples.

    1.Key Properties ntawm FeCrAl Alloy:

    1.High Resistivity: FeCrAl alloys muaj cov hluav taws xob tiv taus siab, uas ua rau lawv siv tau rau hauv cov khoom cua sov.
    2.Excellent Oxidation Resistance: Cov ntsiab lus txhuas ua cov txheej txheem oxide ruaj khov rau ntawm qhov chaw, muab kev tiv thaiv muaj zog tiv thaiv oxidation txawm tias kub kub.

    3.High Temperature Strength: Lawv khaws lawv cov neeg kho tshuab lub zog thiab qhov ruaj khov ntawm qhov kub siab, ua rau lawv tsim nyog rau qhov chaw kub kub.
    4.Good Formability: FeCrAl alloys tau yooj yim fabricated rau hauv xov hlau, ribbon, los yog lwm yam duab siv rau hluav taws xob cua sov.
    5.Corrosion Resistance: Lub alloy resists corrosion nyob rau hauv ntau qhov chaw, ntxiv rau nws durability.
