Qalabka birta ah ee sida caadiga ah loo isticmaalo waxaa ka mid ah birta jilicsan, aluminium, copper, silver, lead, austenitic ahama birta, iyo alloys-ku salaysan nikkel sida Monel, Hastelloy, iyo Inconel. Xulashada walxaha birta ah ee kala duwan waxay ugu horreyn ku saleysan tahay arrimo ay ka mid yihiin cadaadiska shaqada, heerkulka, iyo dabeecadda daxalka ah ee dhexdhexaadka ah. Tusaale ahaan, Alloys-ku-salaysan nikkel waxay u adkeysan karaan heerkulka ilaa 1040 ° C, marka laga sameeyo biraha O-rings, waxay xamili karaan cadaadiska ilaa 280 MPa. Alwaaxyada Monel waxay soo bandhigaan iska caabbinta daxalka ee biyaha badda, gaaska fluorine, hydrochloric acid, sulfuric acid, hydrofluoric acid, iyo kuwa ka soo jeeda. Inconel 718 waxay caan ku tahay iska caabbinta kulaylka.
Walxaha birta ah waxa loo samayn karaa gaasyo fidsan, sixiran, ama jiingado ah, iyo sidoo kale elliptical, octagonal, siddooyin laba-gees ah, iyo gaasadaha muraayadaha. Noocyada noocaan ah guud ahaan waxay u baahan yihiin culeysyo daboolan oo sarreeya waxayna leeyihiin cadaadis iyo adkeysi xaddidan, taasoo ka dhigaysa kuwo xasaasi u ah isbedbeddelka heerkulka. Horumarinta tignoolajiyada xidhitaanka, qalabka birta ee kala duwan ayaa sidoo kale lagu dari karaa naqshado cusub si loo abuuro badeecooyin xidhidhiyo cusub iyo teknoolojiyad kor u qaadaya waxqabadka guud ee xidhitaanka. Tusaalaha caadiga ah waa C-ring-ka loo isticmaalo reactors nukliyeerka.
