Izinto zamathuluzi engxubevange zenziwe nge-carbide (ebizwa nge-hard phase) nensimbi (ebizwa nge-binder phase) enobulukhuni obuphezulu nendawo yokuncibilika nge-powder metallurgy. Lapho izinto ezisetshenziswayo ze-alloy carbide ezivame ukusetshenziswa zine-WC, i-TiC, i-TaC, i-NbC, njll., izibophezelo ezivame ukusetshenziswa yi-Co, i-titanium carbide-based binder i-Mo, Ni.
Izici ezingokomzimba nezomshini zezinto ezisetshenziswayo ze-alloy zincike ekubunjweni kwe-alloy, ubukhulu bezinhlayiya ze-powder kanye nenqubo ye-sintering ye-alloy. Izigaba ezinzima kakhulu ezinobunzima obuphezulu kanye nephoyinti eliphezulu lokuncibilika, ukuphakama kokuqina nokushisa okuphezulu kokuqina kwethuluzi le-alloy Uma i-binder ikhula, amandla aphezulu. Ukwengezwa kwe-TaC ne-NbC ku-alloy kunenzuzo ukucwenga okusanhlamvu futhi kuthuthukise ukumelana nokushisa kwe-alloy. I-carbide enosimende evame ukusetshenziswa iqukethe inani elikhulu le-WC ne-TiC, ngakho-ke ubulukhuni, ukumelana nokugqoka kanye nokumelana Ukumelana nokushisa kuphakeme kunokwensimbi yamathuluzi, ukuqina ekamelweni lokushisa kungu-89 ~ 94HRA, futhi ukumelana nokushisa kungu-80 ~ 1000 degrees.
