Product FEATURE
4J29 ntawm 20 ~ 450 ℃ muaj qhov zoo sib xws linear expansion coefficient nrog silicon boron nyuaj iav Curie point yog siab dua, thiab muaj qhov zoo ntawm qhov kub thiab txias lub koom haum stability. Cov oxide zaj duab xis ntawm cov hlau yog tuab thiab tuaj yeem ua tau zoo
zoo infiltrated los ntawm iav, thiab tsis cuam tshuam nrog mercury, ua rau nws haum rau siv nyob rau hauv Nws tsis cuam tshuam nrog mercury thiab yog haum rau siv nyob rau hauv cov twj paj nruag uas muaj mercury tawm. Nws yog cov khoom siv sib khi tseem ceeb rau cov khoom siv hluav taws xob lub tshuab nqus tsev.
4J32 alloy, tseem hu ua Super-Invar alloy, yog ib qho qis-expansion hlau-nickel drilling alloy nrog qis coefficient ntawm expansion nyob rau hauv thaj tsam ntawm 20-100 ° C. Cov hlau tsis muaj coefficient ntawm kev nthuav dav ntawm 20-100 ° C. Cov alloy yog tsim rau siv los ua cov khoom sib khi rau cov khoom siv hluav taws xob.
Daim ntawv thov khoom
4J29 feem ntau yog siv rau cov khoom siv hluav taws xob xws li emission tubes, oscillator tubes, ignition tubes, magnetrons, transistors, sealed plugs, relays, integrated circuits, lead wires, chassis, shells, brackets, etc. Lub koom haum ntawm nws qhov kub thiab txias, kev ua haujlwm yuav tsum tau ua nyob rau hauv qhov kev kho cua sov kom tsim nyog kom ntseeg tau tias cov khoom muaj qhov zoo sib sib zog nqus. Cov khoom siv tau zoo sib sib zog nqus nqus kev ua tau zoo, thaum siv cov khoom siv forging yuav tsum nruj me ntsis kuaj rau huab cua nruj.
4J32 yog tsim rau ntau yam twj paj nruag, ntsuas qhov chaw, kub bimetallic passive txheej thiab resonance kab noj hniav uas yuav tsum tau qhov seem stability.
