Beryllium Copper Reeds muaj cov khoom nram qab no:

1. Beryllium tooj liab reed tuaj yeem rov nias 100, 000 zaug yam tsis muaj deformation
2. Kub thiab txias tsis kam, zoo qaug zog tsis kam, siab conductivity, corrosion kuj
3. Kev tiv thaiv zoo heev ntawm cov khoom siv qis thiab siab.
Yog li dab tsi yog qhov tshwj xeeb shielding nyhuv? Cov ntaub ntawv hauv qab no yog muab los ntawm cov kws tshaj lij kev lag luam thiab cov koom haum kuaj kev tshaj lij:
