Feem ntau ntawm cov khoom lag luam beryllium yog ua los ntawm beryllium hlaws ua los ntawm magnesium txo qis raws li cov khoom siv raw.
ntau npaum li cas, grain loj, thiab kev kho cua sov thiab molding txheej txheem kom tau cov khoom nrog cov khoom sib txawv.
Cov hlau beryllium hlaws tau los ntawm kev txo cov thermal txo ntawm beryllium oxide magnesium yog nyiaj-grey thiab siv los ua cov khoom beryllium.
raw khoom.
Qhov kev tshawb pom pom tias lub ntiaj teb cov beryl reserves yog 1.21 lab tons (xws li beryllium), thiab qhov nruab nrab.
Muab xam ntawm 1450 tons hauv ib xyoos, nws tuaj yeem raug mined rau ntau tshaj 800 xyoo.

Lub zog ntau dua los yog sib npaug rau 320MPA, yield zog 220MPA, elongation 2%, elastic modulus
E300 GPA.
Lub atomic qhov hnyav ntawm beryllium yog me me, lub neutron capture cross section yog me me, lub scattering cross section yog siab, thiab nws yog pob tshab rau X-rays.
Kev sib deev zoo heev.
Ntau yam alloys ntawm beryllium muaj lub cev zoo, txhua yam thiab hluav taws xob.Ntxiv nrog rau ntau dua beryllium tooj liab alloys
hardness, lub zog, zoo hluav taws xob thiab thermal conductivity, zoo heev hnav tsis kam, corrosion kuj thiab kuj
Lub neej qaug zog siab, yog thawj qhov kev xaiv rau kev tsim cov khoom siv tshuab pwm.
Daim ntawv thov teb ntawm beryllium: atomic zog kev lag luam * siv los ua reactor moderator thiab reflector;* siv los ua cov khoom tso cua sov

* Kev tsim cov foob pob hluav taws, missiles, spaceships thiab tawv nqaij;* Nyob rau hauv loj spaceships thiab airships
Cov khoom siv hauv cov nkoj ferry;* Kev tsim cov dav hlau nres, radiators, condensers, cav;
* Tsim cov gyroscopes thiab gyroscopic platforms hauv missiles, spaceships, aircraft inertial navigation systems, acceleration
Degree lub rooj ★ Metallurgical kev lag luam * Ferrous metallurgy:
Beryllium yog ib qho kev daws teeb meem uas muaj zog heev ntawm ferrite, uas ua rau kom muaj zog permeability ntawm hlau * Xim.
Hlau:
Beryllium tooj liab alloy muaj lub zog siab, zoo hluav taws xob conductivity, qaug zog thiab hnav tsis kam.Beryllium aluminium alloy yog lub teeb hauv qhov hnyav.
Siab tawv, kub ua hauj lwm yam teb * Cov cuab yeej, meters, beryllium qhov rais, caij nplooj ntoos hlav hlab;* Kev kuaj xyuas
cov khoom siv, cov pob golf, thiab cov khoom siv hais lus diaphragm;* Beryllium pendulum tsom iav rau kev sib txuas lus thiab kev tshawb nrhiav satellites,
Ib daim iav beryllium rau kev yees duab kub.
Beryllium alloys Beryllium alloys feem ntau poob rau hauv pawg hauv qab no:
Beryllium aluminium alloy, beryllium nickel alloy, beryllium cobalt alloy, beryllium tooj liab alloy thiab lwm yam.
Ntawm lawv, beryllium tooj liab alloy account rau 70% ntawm kev noj beryllium, thiab beryllium tooj liab alloy muab faib ua:
Beryllium bronze, beryllium nickel tooj liab, beryllium cobalt tooj liab, thiab lwm yam.
Ntawm lawv, beryllium bronze muaj qhov ua tau zoo tshaj plaws thiab yog qhov siv dav tshaj plaws.
Cov hauv qab no tsom rau beryllium bronze.
Beryllium bronze yog nag lossis daus hardening alloy uas yog mechanically, tshuaj, thiab corrosion resistant
Qhov tsuas yog non-ferrous alloy nrog zoo ua ke ntawm cov khoom, tom qab kev daws thiab kev laus thaum tshav kub kub kho, nws muaj
Cov hlau tshwj xeeb muaj zog txwv, txwv elastic, txwv tsis pub tawm thiab qaug zog txwv, thiab tib lub sijhawm muaj hluav taws xob siab, thermal conductivity, siab hardness thiab hnav tsis kam, siab creep kuj thiab corrosion kuj,
Nws kuj muaj cov khoom zoo casting, tsis muaj hlau nplaum thiab tsis muaj qhov ci thaum cuam tshuam.
Yog li ntawd, nws tuaj yeem siv dav hauv cov khoom siv hluav taws xob, cov cuab yeej sib txuas lus, aerospace, petrochemical
Kev lag luam, metallurgical mining, automotive appliances, machinery manufacturing and other fields.
