Beryllium tooj liab yog tooj liab-raws li alloys muaj beryllium (Be0.2 ~ 2.75% wt%), uas yog dav siv nyob rau hauv tag nrho cov beryllium alloys.
Nws noj tau ntau tshaj 70% ntawm tag nrho cov kev siv ntawm beryllium nyob rau hauv lub ntiaj teb no niaj hnub no.Beryllium tooj liab yog cov nag lossis daus hardening alloy, uas muaj lub zog siab, hardness, elastic txwv thiab qaug zog txwv tom qab kev kho mob laus, thiab muaj me me elastic hysteresis.
Thiab muaj corrosion kuj (corrosion tus nqi ntawm beryllium bronze alloy nyob rau hauv seawater: (1.1-1.4) × 10-2mm / xyoo. Corrosion qhov tob: (10.9-13.8) × 10-3mm / xyoo.) Tom qab corrosion, lub zog ntawm beryllium tooj liab alloy, Elongation tus nqi tsis muaj kev hloov pauv, yog li nws tuaj yeem khaws cia rau ntau tshaj 40 xyoo hauv dej rov qab,
Beryllium tooj liab alloy yog cov khoom siv tsis tuaj yeem hloov pauv rau submarine cable repeater qauv.
Nyob rau hauv nruab nrab: txhua xyoo corrosion qhov tob ntawm beryllium tooj liab nyob rau hauv ib tug concentration ntawm tsawg tshaj li 80% (ntawm chav tsev kub) yog 0.0012 mus rau 0.1175mm, thiab corrosion yog me ntsis ceev yog hais tias lub concentration yog ntau tshaj 80%.Hnav tsis kam, kub tsis kam, tsis muaj hlau nplaum, siab conductivity, cuam tshuam thiab tsis muaj sparks.Nyob rau tib lub sijhawm, nws muaj qhov zoo fluidity thiab muaj peev xwm los tsim cov qauv zoo.Vim muaj ntau lub zog zoo ntawm beryllium tooj liab alloy, nws tau siv dav hauv kev tsim khoom.
