I-Berryllium iyinsimbi empunga, ilula (ukuminyana ingu-1.848 g/cm3), iqinile, futhi kulula ukwenza ungqimba oluqinile lwe-oxide oluvikelayo endaweni esemoyeni, ngakho-ke iyazinza uma iqhathaniswa negumbi lokushisa.IBeryllium inephuzu lokuncibilika elingu-1285°C, eliphakeme kakhulu kunezinye izinsimbi ezikhanyayo (i-magnesium, i-aluminium).Ngakho-ke, ama-alloys aqukethe i-beryllium alula, aqinile, futhi amelana nokushisa okuphezulu, futhi ayizinto ezikahle zokukhiqiza imishini yezindiza kanye ne-aerospace.Isibonelo, ukusetshenziswa kwe-beryllium alloys ukwenza ama-rocket casings kunganciphisa kakhulu isisindo;ukusetshenziswa kwe-beryllium alloys ukwenza amasathelayithi okwenziwa kanye nemikhumbi-mkhathi kungaqinisekisa ukuphepha kwendiza.

"Ukukhathala" kuyinkinga evamile yezinsimbi ezijwayelekile.Isibonelo, intambo yezintambo ezithwala imithwalo yesikhathi eside izophuka ngenxa "yokukhathala", futhi intwasahlobo izolahlekelwa ukuqina kwayo ngenxa "yokukhathala" uma icindezelwa ngokuphindaphindiwe futhi ikhululekile.I-Metal beryllium inomsebenzi wokulwa nokukhathala.Isibonelo, engeza cishe u-1% we-beryllium yensimbi ensimbi encibilikisiwe.Intwasahlobo eyenziwe ngale nsimbi ye-alloy ingakwazi ukwelula izikhathi eziyizigidi ezingu-14 ngokuqhubekayo ngaphandle kokulahlekelwa ukuqina ngenxa "yokukhathala", ngisho nasesimweni "sokushisa okubomvu" Ngaphandle kokulahlekelwa ukuguquguquka kwayo, ingachazwa ngokuthi "i-indomitable".Uma cishe u-2% we-beryllium yensimbi yengezwa ethusi, amandla aqinile kanye nokunwebeka kwaleli ngxube ye-beryllium yethusi akufani nensimbi.Ngakho-ke, i-beryllium yaziwa ngokuthi "insimbi engamelana nokukhathala".

Esinye isici esibalulekile se-beryllium yensimbi ukuthi ayinhlansi lapho ishaya, ngakho-ke ama-alloys e-copper-nickel aqukethe i-beryllium avame ukusetshenziselwa ukwenza izinsimbi “ezingashi,” izando, imimese namanye amathuluzi, asetshenziswa ngokukhethekile ekucubunguleni izinto ezivuthayo neziqhumayo.

I-Metal beryllium nayo inendawo yokubeka obala emisebeni.Uma sithatha ama-X-ray njengesibonelo, amandla okungena i-beryllium anamandla ngokuphindwe izikhathi ezingu-20 kunelomthofu futhi anamandla aphindwe izikhathi ezingu-16 kunethusi.Ngakho-ke, i-beryllium yensimbi inegama elithi "ingilazi yensimbi", futhi i-beryllium ivame ukusetshenziselwa ukwenza "amafasitela" amashubhu e-X-ray.

I-Metal beryllium nayo inomsebenzi omuhle wokudlulisa umsindo.Ijubane lokusabalalisa lomsindo ku-beryllium yensimbi liphezulu njenge-12,600 m/s, ephakeme kakhulu kunejubane lomsindo emoyeni (340 m/s), amanzi (1500 m/s) nensimbi (5200 m/s) .ithandwa yimboni yezinsimbi zomculo.
