Chimodzi mwazinthu zopangira mphamvu zamkuwa zomwe zimapezeka pamsika masiku ano ndi mkuwa wa beryllium, womwe umadziwikanso kuti mkuwa wa masika kapena mkuwa wa beryllium. Magulu amalonda a beryllium mkuwa ali ndi 0.4 mpaka 2.0 peresenti ya beryllium. Chiŵerengero chaching'ono cha beryllium ndi mkuwa chimapanga banja lazitsulo zamkuwa zapamwamba zokhala ndi mphamvu zokwera ngati chitsulo cha alloy. Yoyamba mwa mabanja awiriwa, C17200 ndi C17300, imaphatikizapo mphamvu zapamwamba zokhala ndi zolimbitsa thupi, pamene banja lachiwiri, C17500 ndi C17510, limapereka ma conductivity apamwamba ndi mphamvu zochepa. Makhalidwe abwino a ma aloyiwa ndi momwe amayankhira pamankhwala oletsa mvula, matenthedwe abwino kwambiri, komanso kukana kupumula kupsinjika.
