Ib qho ntawm lub zog siab tshaj plaws tooj liab raws li alloys muaj nyob rau hauv kev ua lag luam niaj hnub no yog beryllium tooj liab, tseem hu ua caij nplooj ntoos hlav tooj liab lossis beryllium bronze. Cov qib lag luam ntawm beryllium tooj liab muaj 0.4 mus rau 2.0 feem pua ​​beryllium. Qhov sib piv me me ntawm beryllium rau tooj liab tsim ib tsev neeg ntawm cov tooj liab siab nrog lub zog siab li cov hlau alloy. Thawj ntawm ob tsev neeg, C17200 thiab C17300, suav nrog lub zog siab nrog kev ua haujlwm nruab nrab, thaum tsev neeg thib ob, C17500 thiab C17510, muaj kev ua haujlwm siab nrog lub zog nruab nrab. Cov yam ntxwv tseem ceeb ntawm cov alloys no yog lawv cov lus teb zoo heev rau kev kho nag lossis daus-tawv tawv, zoo thermal conductivity, thiab tiv thaiv kev ntxhov siab.
