Chitoliro cha aloyi ndi mtundu wa chitoliro chachitsulo chosasunthika, ntchito yake ndi yokwera kwambiri kuposa chitoliro chachitsulo chosasunthika, chifukwa mtundu uwu wa chitoliro chachitsulo uli ndi Cr, kukana kwake kutentha kwambiri, kukana kutentha kwapansi, kukana kwa dzimbiri ndikwabwino kuposa zina. Chitoliro chachitsulo , kotero chitoliro cha alloy chimagwiritsidwa ntchito kwambirimu petroleum, ndege, mankhwala, mphamvu yamagetsi, boiler, asilikali ndi mafakitale ena.
Aloyi chubu amatanthauza ntchito aloyi extrusion processing mu zitsulo tubular zakuthupi, amene akhoza kukhala chimodzi kapena zingapo chatsekedwa mabowo, khoma makulidwe ndi yunifolomu gawo mtanda, ntchito magalimoto, zombo, Azamlengalenga, ndege, magetsi, ulimi, electro makina, nyumba ndi mafakitale ena.
