FeNiCr alloy yog iav sealed alloy FeNiCr departments sawv cev ntawm lub hom.Cov pab pawg neeg hlau ntawm lub Hoobkas siv lub sij hawm ntev, ruaj khov kev ua tau zoo.Mainly siv los ua txhua yam ntawm lub tshuab nqus tsev twj, xws li hluav taws xob raj anode caps, thiab lwm yam. yuav tsum tau xaiv nyob rau hauv daim ntawv thov ntawm kev sib piv expansion coefficient ntawm iav thiab hlau.In thiaj li yuav txhim kho lub sealing zog ntawm hlau thiab iav tso cai rau cov alloy uas muaj txhuas, cerium.Thaum kho cua sov, grain loj heev, yuav tsum tau zam kom lub strip nrog zoo sib sib zog nqus nqus txuas ntxiv kev ua tau zoo thiab huab cua nruj.
