Raws li tau hais los saum no, kwv yees li 30% ntawm cov beryllium uas tsim nyob rau hauv lub ntiaj teb no txhua xyoo yog siv los tsim cov khoom thiab cov khoom muaj feem xyuam rau lub teb chaws ruaj ntseg cov cuab yeej thiab cov cuab yeej xws li reactors, foob pob ua ntxaij, missiles, spacecraft, aircraft, submarines, thiab lwm yam. lub zog fuels rau foob pob hluav taws, missiles, thiab dav hlau dav hlau.
Kwv yees li 70% ntawm feem ntau beryllium yog siv nyob rau hauv cov pa industries, xws li alloying ntsiab, ntxiv tsawg tshaj li 2% ntawm Be rau tooj liab, npib tsib xee, txhuas, magnesium tuaj yeem ua rau muaj kev cuam tshuam loj heev, lub npe nrov tshaj plaws yog beryllium tooj liab, Lawv yog Cu- Ua alloys nrog Be cov ntsiab lus tsawg dua 3%, uas yog siv dav hauv kev lag luam.Piv txwv li, muaj 6 hom deformed tooj liab-beryllium alloys (C17XXX alloys) suav nrog ASTM tus qauv hauv Tebchaws Meskas, thiab cov ntsiab lus Be yog 0.2% ~ 2.00%;7 hom cam khwb cia tooj liab-beryllium alloys (C82XXX) nrog cov ntsiab lus ntawm 0.23% ~ 2.85%.Beryllium tooj liab muaj cov khoom zoo heev.Nws yog ib qho tseem ceeb heev tooj liab alloy thiab tau dav siv nyob rau hauv ntau yam kev lag luam ntawm lub teb chaws.Tsis tas li ntawd, npib tsib xee-beryllium alloy, aluminium-beryllium alloy thiab steel kuj siv qee cov beryllium.Kev siv ntawm beryllium hauv beryllium-muaj alloys suav txog li 50% ntawm tag nrho, thiab tus so yog siv hauv iav tsim thiab hauv kev lag luam ceramic hauv daim ntawv ntawm beryllium oxide.
