Umuringa hamwe na beryllium nkibintu byingenzi bigize amavuta kandi nta mabati.Irimo 1,7-2.5% beryllium hamwe na nikel nkeya, chromium, titanium nibindi bintu.Nyuma yo kuzimya no kuvura gusaza, imbaraga ntarengwa zishobora kugera kuri 1250-1500MPa, yegereye urwego rwicyuma giciriritse.Mugihe kizimye, plastike nibyiza cyane kandi irashobora gutunganyirizwa mubicuruzwa bitandukanye byarangije.Umuringa wa Beryllium ufite ubukana bwinshi, imipaka ya elastike, umunaniro ntarengwa no kwambara.Ifite kandi imbaraga zo kurwanya ruswa, amashanyarazi yumuriro nu mashanyarazi.Ntabwo itanga ibishashi iyo byatewe.Irakoreshwa cyane nkibice byingenzi bya elastike nibice bidashobora kwambara.Nibikoresho biturika biturika, nibindi
Bikoreshwa mu gusudira intwaro, imbunda zo gusudira hamwe nibikoresho byo gusudira ku bikoresho binini byo gusudira nk'imodoka n'amato
