Ko te parahi Beryllium he koranu e hangai ana ki te parahi kei roto he beryllium (Be0.2～2.75%wt%), e whakamahia nuitia ana i roto i nga koranu beryllium katoa.
Ko tana kai kua neke ake i te 70% o te kohinga katoa o te beryllium i te ao i enei ra.Ko te parahi Beryllium he koranu whakamaroke i te rerenga, he kaha te kaha, he pakeke, he tepe rapa me te tepe ngenge i muri i te maimoatanga tawhito o te otinga, a he iti nei te histeresis elastic.
A he parenga waikura (te reiti waikura o te koranu parahi beryllium i roto i te wai moana: (1.1-1.4)×10-2mm/tau. Te hohonu o te waikura: (10.9-13.8)×10-3mm/tau.) I muri i te waikura, te kaha o te parahi beryllium. koranu , Ko te tere o te Elongation kaore he huringa, na reira ka taea te pupuri mo te neke atu i te 40 tau i roto i te hokinga wai,
Ko te koranu parahi Beryllium he rauemi e kore e taea te whakakapi mo te hanganga tukurua taura o raro.
I roto i te reo: ko te hohonu o te waikura a-tau o te parahi beryllium i te kukū o te iti iho i te 80% (i te pāmahana rūma) ko te 0.0012 ki te 0.1175mm, ka paku te tere o te waikura ki te nui ake te kukū i te 80%.Ka mau i te parenga, te iti o te pāmahana, te kore-aukume, te kaha o te kawe, te awe me te kore korakora.I te wa ano, he pai te rere me te kaha ki te whakaputa i nga tauira pai.Na te maha o nga ahuatanga pai o te koranu parahi beryllium, kua whakamahia nuitia ki te hanga.
