Chithovu chachitsulo ndi mtundu watsopano wazinthu zokhala ndi mphamvu zambiri, zolemera zopepuka, zotenthetsera kutentha kwambiri, kutsekemera kwa mawu ndi mphamvu zoyamwitsa mphamvu, zomwe zingagwiritsidwe ntchito muzamlengalenga, magalimoto, mphamvu, zomangamanga ndi zina. Zida zodziwika bwino zazitsulo za thovu zimaphatikizapo

Aluminiyamu thovu: opangidwa ndi mkulu chiyero zotayidwa zakuthupi kudzera kukulitsa, kudula, kuwotcherera, extrusion ndi njira zina, ndi madutsidwe kwambiri matenthedwe madutsidwe, madutsidwe magetsi ndi processability.
Chithovu chamkuwa: chopangidwa ndi zinthu zamkuwa zoyera kwambiri kudzera munjira yofanana ndi chithovu cha aluminiyamu, chokhala ndi mphamvu yayikulu, mphamvu zamagetsi komanso kukana dzimbiri.
Chithovu cha Titaniyamu: Chopangidwa kuchokera ku zinthu zoyera kwambiri za titaniyamu kudzera munjira yofanana ndi thovu la aluminiyamu, yolimba kwambiri, kukhazikika kwamafuta komanso kukana dzimbiri.
Chithovu cha Nickel: Chopangidwa ndi zinthu zoyera kwambiri za nickel kudzera m'njira yofanana ndi thovu la aluminiyamu, yokhala ndi mphamvu yabwino kwambiri yamagetsi komanso kukana dzimbiri.
Chithovu cha Zinc: chopangidwa ndi zinthu zoyera kwambiri za zinc kudzera munjira yofanana ndi thovu la aluminiyamu, yokhala ndi kachulukidwe kakang'ono komanso mphamvu yabwino kwambiri yotchinjiriza.
Kuphatikiza pa zida zachitsulo zomwe zili pamwambazi, palinso zinthu zina, monga thovu la tungsten, thovu lachitsulo, thovu la magnesium, ndi zina. Zida zosiyanasiyana zachitsulo zimakhala ndi katundu wosiyanasiyana komanso magawo ogwiritsira ntchito, omwe amatha kusankhidwa malinga ndi zosowa zenizeni.
