Cov hlau ua kom sov tseem ceeb yog "lub plawv" ntawm txhua yam khoom siv cua sov. Hauv qab no yog cov yam ntxwv tseem ceeb, qhov zoo, thiab kev siv ntawm peb cov khoom siv hlau ua kom sov - tsim los ua kom tau raws li ntau yam kev xav tau ntawm qhov kub thiab kev ua tau zoo:

Hom hlau nplaum	Kev Sau Ntawv & Cov Ntsuas Tseem Ceeb	Cov txiaj ntsig tseem ceeb	Cov Ntawv Thov
Nickel-Chromium (Ni-Cr)	Ni80Cr20/Ni60Cr15; Kev Tiv Thaiv: 1.0–1.5Ω·mm²/m; Kub Tshaj Plaws: 1200°C (txuas ntxiv)	Kev tiv thaiv oxidation zoo heev; kev hloov pauv tsis kam (± 1% tom qab 5000h); kev faib cua sov sib xws; lub neej ua haujlwm ntev (≥8000h)	Cov cub tawg kub kub hauv kev lag luam, cov khoom siv cua sov hluav taws xob, cov tshuab luam ntawv 3D hotends, cov tshuab cua sov aerospace
Hlau-Chromium-Aluminium (Fe-Cr-Al)	Cr20Al5/Cr18Al2; Kev Tiv Thaiv: 1.2–1.6Ω·mm²/m; Kub Tshaj Plaws: 1400°C (txuas ntxiv)	Kev tiv taus kub heev; pheej yig; lub teeb yuag; lub zog kho tshuab zoo; corrosion-resistant rau industrial gases	Cov khoom siv hauv chav ua noj ua haus (qhov cub, qhov cub ci), cov cua sov hauv cov kav dej lag luam, cov cua sov hauv tsev, cov khoom siv cua sov hauv chav kuaj mob
Tooj liab-Nickel (Cu-Ni)	Cu55Ni45 (Constantan); Kev Tiv Thaiv: 0.45Ω·mm²/m; Kub Tshaj Plaws: 500°C (txuas ntxiv)	Qhov kub tsis tshua muaj coefficient ntawm kev tiv thaiv (TCR: ± 20ppm/°C); ruaj khov heev; tswj tau qhov kub kom meej; tsis muaj hlau nplaum	Cov ntsuas kub uas raug, cov khoom siv kho mob (teeb kho hniav), cov khoom cua sov uas kub qis, cov hluav taws xob tam sim no rau cov tshuab tswj cua sov

Vim li cas ho xaiv peb cov khoom siv cua sov uas ua los ntawm cov hlau alloy?

Zoo Tshaj Plaws Alloy Zoo: Tag nrho cov hlau alloys yog vacuum-yaj nrog kev tswj hwm kev tsis huv (ua kom muaj kev tiv thaiv thiab cua sov tso tawm thoob plaws cov khoom.)

Kev Ua Tau Zoo Raws Li Koj Xav TauXaiv Ni-Cr rau qhov ruaj khov siab, Fe-Cr-Al rau qhov kub thiab txias heev, lossis Cu-Ni rau kev tswj qhov tseeb—khwv tau 500°C–1400°C kev ua haujlwm.

Kev Sib Koom Ua Ke ntawm Cov CheebtsamPeb cov khoom cua sov muab cov hlau sib xyaw ua ke nrog cov khoom rwb thaiv tsev zoo thiab cov khoom sib txuas, txo qhov poob hluav taws xob los ntawm 12% piv rau cov khoom lag luam dav dav.
