Q:Yeyiphi eyomeleleyo phakathi kwee-rivets zobhedu kunye nee-rivets zobhedu?
AUbhedu olusulungekileyo, olukwabizwa ngokuba lubhedu olubomvu, lunoxinaniso lwe (7.83g/cm3) kunye nendawo yokunyibilika yee-degrees ezingama-1083. Ayinamagnetic. Inokuqhuba kakuhle, i-thermal conductivity, ukumelana nokubola kunye nokuqina.
Ubuninzi bobhedu (8.93g / cm3) busetyenziselwa ukufakwa kwi-lining bush mechanical bearing bush, ekwazi ukunxiba.
Ubuninzi "bobhedu" buphezulu kunobhedu obomvu, kwaye "ubhedu" lukhuni kunye nokuqina okulungileyo.
