Mas siv nyob rau hauv ob thaj chaw rau kev hloov pauv hluavtaws zog thiab kev ua haujlwm
Hauv kev lag luam muaj zog, feem ntau nyob rau hauv lub siab sib nqus teb tau muaj kev sib nqus siab thiab muaj kev sib nqus ntawm cov alloy. Hauv kev lag luam hluav taws xob, feem ntau ntawm cov alloy tsawg lossis nruab nrab muaj lub siab sib nqus permeability thiab quab yuam kom yuam. Ntawm cov siab heev yuav tsum tau ua ntawm ib txoj hlua nyias lossis alloy muaj kev tiv taus loj dua. Feem ntau nrog daim ntawv lossis sawb.
Cov ntaub ntawv sib nqus me me hauv kev sib pauv rau siv, vim muaj kev sib nqus eddy urnness, ntau dua qhov tsawg dua ntawm kev sib nqus sib nqus, cov ntau dua tam sim no poob ntau dua, nqus txo tau ntau dua. Rau qhov no, cov khoom yuav tsum tau ua cov ntawv rho (cov txheej txheem rho tawm nrog cov txheej txheem oxide, lossis cov alloys feem ntau siv cov hlautes politectesis txheej.
Hlau-Nickel alloy feem ntau nyob rau hauv kev sib yuav sib nqus teb siv, feem ntau rau cov quab yuam hlau, relay, cov hluav taws xob me me.
Cov hauv qab no yog cov ntsiab lus ntawm peb cov khoom 1J80:
