Isinyithi esihle kakhulu sombhobho sixhomekeke kwisicelo esithile kunye neemfuno. Ngokomzekelo, isinyithi esingenasici sihlala sisetyenziselwa ukuxhathisa ukubola kunye nokuqina, okwenza kube yinto efanelekileyo kwizicelo apho umgqomo ubonakaliswe kwiindawo ezinzima okanye izinto eziphazamisayo. Nangona kunjalo, ezinye isinyithi ezifana ne-carbon steel okanye i-aluminium inokuthi ifaneleke ngakumbi kwiimeko ezahlukeneyo ngokusekelwe kwizinto ezifana neendleko, ubunzima kunye neemfuno ezithile zokusebenza. Kubalulekile ukuqwalasela iimfuno ezithile zemipu yakho kwaye udibane neengcali zezixhobo ukugqiba isinyithi esifanelekileyo somsebenzi.

Imolybdenum ayiyomelelanga ngokubanzi kunentsimbi kuba imolybdenum isoloko isetyenziswa njengesixhobo sokudibanisa kwintsimbi ukomeleza amandla ayo, ukuqina, kunye nokuxhathisa umhlwa. Xa ifakwe kwintsimbi kwiimali ezifanelekileyo, i-molybdenum inokuphucula kakhulu iimpawu ze-mechanical zensimbi, iyenze ifaneleke ngakumbi kwizicelo ezixinzelelekileyo ezifana nokuveliswa kwe-alloys yensimbi ephezulu, kuquka i-chromium-molybdenum steels.

I-molybdenum ecocekileyo yintsimbi ephikisayo enendawo yokunyibilika ephezulu kunye namandla abalaseleyo obushushu obuphezulu, kodwa iqhele ukusetyenziswa njengesixhobo sokudibanisa kwintsimbi ukukhulisa iipropathi zayo kunokuba ibe yodwa kwizicelo zolwakhiwo. Ngoko ngelixa i-molybdenum ngokwayo ingenawo amandla kunentsimbi, njengento edibeneyo inokudlala indima ebalulekileyo ekwandiseni amandla kunye neempawu zentsimbi.

Imipu yemipu iqhele ukwenziwa kwiindidi ezahlukeneyo zentsimbi, kubandakanya intsimbi engatyiwa, intsimbi yekhabhoni, kunye nentsimbi yealloyi. Ezi zixhobo zikhethwe ngenxa yokomelela kwazo, ukuqina, kunye nokukwazi ukumelana noxinzelelo oluphezulu kunye namaqondo obushushu enziwa ngexesha lokudubula kompu. Ukongeza, eminye imigqomo inokwenziwa kwiialloys ezikhethekileyo zentsimbi, njengentsimbi yechromoly, enika amandla okwandisiweyo kunye nokumelana nobushushu. Uhlobo oluthile lwentsimbi esetyenziselwa umbhobho wompu luxhomekeke kwizinto ezifana nokusetyenziswa okujoliswe kuyo kompu, iimpawu zokusebenza ezifunekayo, kunye nenkqubo yokuvelisa esetyenziswa ngumenzi wesibhamu.
