Zida za aloyi zimapangidwa ndi carbide (yotchedwa hard phase) ndi chitsulo (yotchedwa binder phase) yokhala ndi kuuma kwakukulu ndi malo osungunuka kudzera muzitsulo za ufa.Momwe zida za alloy carbide zida zomwe zimagwiritsidwa ntchito kwambiri zimakhala ndi WC, TiC, TaC, NbC, ndi zina zambiri, zomangira zomwe zimagwiritsidwa ntchito kwambiri ndi Co, titanium carbide-based binder ndi Mo, Ni.
The thupi ndi makina katundu wa aloyi chida zipangizo zimadalira zikuchokera aloyi, makulidwe a particles ufa ndi sintering ndondomeko aloyi.Magawo ovuta kwambiri okhala ndi kuuma kwakukulu ndi malo osungunuka kwambiri, amakweza kuuma ndi kutentha kwakukulu kwa chida cha alloy Pamene binder imakwera kwambiri, imakhala yokwera kwambiri.Kuphatikizika kwa TaC ndi NbC ku alloy ndikopindulitsa kuyeretsa mbewu ndikuwongolera kukana kutentha kwa alloy.Carbide yomwe imagwiritsidwa ntchito nthawi zambiri imakhala ndi WC ndi TiC wambiri, kotero kuuma, kukana kuvala ndi kukana Kukana kutentha ndikwambiri kuposa chitsulo chachitsulo, kuuma kwa kutentha ndi 89 ~ 94HRA, ndi kukana kutentha ndi 80 ~ 1000 madigiri.
