Peb paub tias txo qhov hnyav ntawm lub dav hlau tuaj yeem txuag tau ntawm cov nqi xa tawm.Raws li ib qho tseem ceeb lub teeb hlau, beryllium yog tsawg dua ntom dua txhuas thiab muaj zog dua hlau.Yog li ntawd, beryllium yog ib qho tseem ceeb heev aerospace khoom.Beryllium-aluminium alloys, uas muaj qhov zoo ntawm ob qho tib si beryllium thiab txhuas, yog dav siv los ua cov khoom siv rau cov tsheb hauv chaw, xws li cov khoom siv satellites thiab spaceships.Lub hauv paus ncej, kab teeb kab thiab ruaj truss Liang li al.

Alloys uas muaj beryllium kuj yog cov ntaub ntawv zoo rau kev tsim cov dav hlau, thiab beryllium tuaj yeem pom nyob rau hauv cov khoom tseem ceeb xws li rudders thiab tis thawv.Nws tau tshaj tawm tias hauv lub dav hlau loj niaj hnub no, txog 1,000 qhov chaw yog ua los ntawm beryllium alloy.
Hauv lub nceeg vaj hlau, beryllium muaj cov khoom siv thermal zoo, thiab muaj cov khoom zoo heev xws li cov ntsiab lus melting siab, siab tshwj xeeb kub, siab thermal conductivity thiab haum thermal expansion tus nqi.Yog tias beryllium siv los tsim cov khoom siv braking rau lub dav hlau supersonic, nws muaj cov cua sov zoo heev thiab cov khoom cua sov.Kev siv beryllium los ua "cov tsho tiv thaiv cua sov" rau cov khoom siv hluav taws xob thiab cov khoom siv dav hlau tuaj yeem ua kom ntseeg tau tias lawv qhov kub thiab txias yuav tsis nce siab thaum lawv dhau los ntawm huab cua, yog li ua kom muaj kev nyab xeeb ntawm lub dav hlau.Nyob rau tib lub sijhawm, hlau beryllium kuj tseem yog cov khoom siv tseem ceeb rau kev tsim cov tshuab inertial navigation, uas yog qhov tseem ceeb rau kev txhim kho qhov tseeb navigation ntawm missiles, aircraft, thiab submarines.Vim tias beryllium muaj qhov cuam tshuam zoo rau lub teeb infrared, nws kuj yog siv rau hauv qhov chaw kho qhov muag.
