Precision Alloy Hlau Nickel Hlau Invar / Vacodil36 / Feni36 rau Sealing iav
Invar/ Vacodil36 /Peb 36Hlau rau Sealing Glass
Kev faib tawm: qis coefficient ntawm thermal expansion alloy
Daim ntawv thov: Invar yog siv qhov kev ruaj ntseg siab, xws li cov cuab yeej precision, moos, seismic creep gauges, TV duab ntxoov ntxoo-mask thav duab, li qub hauv motors, thiab antimagnetic watches. Hauv kev soj ntsuam av, thaum thawj qhov kev txiav txim siab (high-precision) nce qib yuav tsum tau ua, cov qib qib siv tau ua los ntawm Invar, tsis yog ntoo, fiberglass, lossis lwm yam hlau. Invar struts tau siv nyob rau hauv qee lub pistons los txwv lawv cov thermal expansion hauv lawv lub tog raj kheej.
