Vim nws qhov hnyav thiab qhov hnyav, tungsten feem ntau yog siv los ua ib qhocounterweight hlau. Nws cov khoom ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev cog lus compact thiab hnyav hnyav. Txawm li cas los xij, nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov, lwm yam hlau xws li txhuas, hlau, thiab qee zaum txawm tias depleted uranium tuaj yeem siv los ua qhov hnyav. Txhua lub hlau muaj nws tus kheej zoo thiab kev xav, thiab kev xaiv ntawm cov hlau counterweight nyob ntawm cov yam ntxwv xws li qhov ntom ntom, tus nqi, kev nyab xeeb, thiab kev cuam tshuam ib puag ncig.

Tungsten yog siv rau hauv counterweights vim nws siab ceev thiab hnyav hnyav. Tungsten muaj qhov ntom ntawm 19.25 g / cm3, uas yog siab dua li lwm cov hlau siv xws li txhuas lossis hlau. Qhov no txhais tau hais tias qhov ntim me me ntawm tungsten tuaj yeem muab qhov hnyav tib yam li lub ntim loj ntawm lwm cov ntaub ntawv.

Kev siv cov tungsten hauv cov khoom hnyav tso cai rau ntau qhov kev cog lus, txuag qhov chaw, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov hnyav faib yog qhov tseem ceeb. Tsis tas li ntawd, tungsten yog tsis muaj tshuaj lom thiab muaj lub siab melting point, ua rau nws muaj kev nyab xeeb thiab ruaj khov xaiv rau kev siv counterweight.

Vim nws cov khoom tshwj xeeb, tungsten feem ntau suav hais tias zoo dua li cov hlau hauv qee yam kev siv. Nov yog qee qhov laj thawj vim li cas tungsten yuav zoo dua li cov hlau hauv qee qhov xwm txheej:

1. Ceev: Tungsten muaj qhov ntom ntom ntau dua li cov hlau, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau ua kom zoo hauv ib lub ntim me me. Qhov no yog tshwj xeeb tshaj yog pab tau thaum yuav tsum tau ib tug compact thiab hnyav counterweight.

2. Hardness: Lub hardness ntawm tungsten yog ho siab dua hlau, uas ua rau nws ntau resistant rau hnav, khawb thiab deformation. Cov cuab yeej no muaj txiaj ntsig zoo hauv kev siv xws li cov cuab yeej txiav, riam phom tho riam phom thiab qhov chaw kub kub.

3. Kub kub tsis kam: Lub melting point ntawm tungsten yog siab heev, ntau dua li ntawm cov hlau. Qhov no ua rau nws tsim nyog siv rau hauv cov ntawv thov uas muaj qhov kub thiab txias yog qhov xav tau, xws li aerospace thiab kev siv tub rog.

4. Tsis muaj tshuaj lom: tungsten tsis muaj tshuaj lom, tsis zoo li qee hom hlau alloys uas yuav muaj cov khoom uas ua rau muaj kev phom sij rau kev noj qab haus huv thiab ib puag ncig.

Txawm li cas los xij, nws tsim nyog sau cia tias cov hlau tseem muaj nws tus kheej zoo, xws li nws cov khoom siv ntau yam, ductility, thiab tus nqi qis dua piv rau tungsten. Qhov kev xaiv ntawm tungsten thiab steel nyob ntawm seb qhov yuav tsum tau ua ntawm daim ntawv thov thiab qhov kev ua tau zoo uas yuav tsum tau muaj rau cov ntaub ntawv siv.
