Ityhubhu ye-alloy inokwahlulwahlulwa ibe: ityhubhu ye-alloy ephantsi, ityhubhu yesakhiwo se-alloy, ityhubhu ye-alloy ephezulu, ityhubhu ye-stainless ye-asidi engatshiyo, ityhubhu ye-alloy enobushushu obuphezulu.

Iityhubhu zentsimbi zemibhobho, izixhobo zobushushu, ishishini loomatshini, ipetroliyam, ukubhola kwejoloji, isikhongozeli, ishishini leekhemikhali, iityhubhu zentsimbi zenjongo ekhethekileyo, nezinye iinjongo.

Inkqubo yokuvelisa yahlukile, kwaye yahlulwe yaba yityhubhu yentsimbi engenamthungo eshushu (extrusion) kunye netyhubhu yentsimbi engenamthungo ebandayo (eqengqelekayo) enemithungo emibini.

Iityhubhu zentsimbi ezigoqekileyo ezishushu zihlulwe zibe ziityhubhu zentsimbi ngokubanzi, iityhubhu zebhoyila ezinoxinzelelo oluphantsi noluphakathi, iityhubhu zebhoyila ezinoxinzelelo oluphezulu, iityhubhu zentsimbi ye-alloy, iityhubhu zentsimbi engatyiwayo, iityhubhu zokuqhekeka kwepetroliyam, iityhubhu zejiyoloji kunye nezinye iityhubhu zentsimbi.

Umbhobho wentsimbi engenamthungo oqengqelekayo (ocoliweyo) ukongeza kumbhobho wentsimbi ngokubanzi, umbhobho wentsimbi yebhoyila ophantsi nophakathi, umbhobho wentsimbi yebhoyila ophantsi, umbhobho wentsimbi ye-alloy, umbhobho wentsimbi engatyiwayo, umbhobho wokuqhekeka kwepetroliyam, omnye umbhobho wentsimbi, uquka umbhobho wentsimbi obhityileyo onezidonga zekhabhoni, umbhobho wentsimbi obhityileyo onezidonga ze-alloy, umbhobho wentsimbi engatyiwayo, umbhobho wentsimbi enemilo ekhethekileyo. Iikhrayitheriya ziquka:GB/T8162-2008 (ityhubhu yentsimbi engenamthungo yesakhiwo), GB/T8163-2008 (ityhubhu yentsimbi engenamthungo yokuthutha ulwelo),GB3087-2008 (ityhubhu yentsimbi engenamthungo yebhoyila yoxinzelelo oluphantsi noluphakathi),GB5310-2008 (ityhubhu yentsimbi engenamthungo yebhoyila yoxinzelelo oluphezulu), GB5312-2009 (ityhubhu yentsimbi engenamthungo yentsimbi yekhabhoni kunye nentsimbi yekhabhoni yemanganese yeenqanawa),GB6479-2013 (ityhubhu yentsimbi engenamthungo yezixhobo zesichumiso esinoxinzelelo oluphezulu), njl.
