Xa isinyithi okanye i-alloy ikwimo eqinile, unyango lobushushu lubhekisela kwinkqubo edibanisa imisebenzi yokufudumeza kunye nokupholisa. Ukunyangwa kobushushu kusetyenziselwa ukuguqula ukuthamba, ukuqina, i-ductility, ukukhululeka koxinzelelo, okanye amandla ezinto zokubopha eziye zafumana unyango lobushushu. Ukunyangwa kokushisa kusetyenziswe kuzo zombini izibophelelo ezigqityiweyo kunye neengcingo okanye imivalo eyenza i-fasteners ngokuyidibanisa ukuze itshintshe i-microstructure yazo kwaye iququzelele imveliso.
Xa isetyenziswe kwisinyithi okanye i-alloy ngelixa isekho kwimo eqinile, unyango lobushushu ludibanisa ukufudumeza kunye neenkqubo zokupholisa. Xa ujongene ne-fasteners eye yafumana unyango lobushushu, unyango lobushushu lusetyenziselwa ukuvelisa utshintsho kwi-softness, ukuqina, i-ductility, i-stress relief, okanye amandla. Ukongeza ekutshiseni, iingcingo okanye imivalo eyenziwe ngayo i-fasteners nayo ishushu ngexesha lenkqubo yokucoca ukuze utshintshe i-microstructure yazo kwaye iququzelele imveliso.
Iinkqubo kunye nezixhobo zonyango lwe-thermal ziza kwiindidi ezininzi. Ezona ntlobo zithandwayo zeziko ezisetyenziswayo xa iziqhoboshi zokuphatha ubushushu yibhanti engaguqukiyo, irotary, kunye nebhetshi. Abantu abasebenzisa unyango lobushushu bakhangela iindlela zokonga amandla kunye nokucutha iindleko eziluncedo ngenxa yexabiso eliphezulu lemithombo yamandla njengombane kunye negesi yendalo.
Ukuqina kunye nokufudumeza amagama amabini asetyenziselwa ukuchaza inkqubo yobushushu. Ukulandela ukucima (ukupholisa ngokukhawuleza) ngokuntywiliselwa kwentsimbi kwioli, ukuqina kwenzeka xa iintsimbi ezithile zifudunyezwa kwiqondo lokushisa eliguqula isakhiwo sentsimbi. Ngaphezulu kwe-850 ° C yiqondo lokushisa elincinci elifunekayo kwinguqu yesakhiwo, nangona lo bushushu bunokutshintsha ngokusekelwe kwisixa sekhabhoni kunye nezinto ezixutywayo ezikhoyo kwintsimbi. Ukunciphisa ubuninzi be-oxidation kwintsimbi, umoya wesithando somlilo ulawulwa.
