Izixhobo ze-alloy zenziwe nge-carbide (ebizwa ngokuba yi-hard phase) kunye ne-metal (ebizwa ngokuba yi-binder phase) enobunzima obuphezulu kunye nendawo yokunyibilika ngokusebenzisa i-powder metallurgy. Apho izixhobo ze-alloy carbide ezisetyenziswa rhoqo zine-WC, TiC, TaC, NbC, njl.njl., izixhobo ezisetyenziswa rhoqo yi-Co, i-titanium carbide-based binder yi-Mo, Ni.
Iimpawu zomzimba nezoomatshini zezinto zesixhobo se-alloy zixhomekeke kulwakhiwo lwe-alloy, ubukhulu bee-powder particles kunye nenkqubo yokusila kwe-alloy. Okukhona ii-phases zinzima kakhulu ezinobunzima obuphezulu kunye nendawo yokunyibilika ephezulu, kokukhona ubunzima kunye nobunzima obuphezulu besixhobo se-alloy buphakama. Okukhona i-binder ininzi, kokukhona amandla aphezulu. Ukongezwa kwe-TaC kunye ne-NbC kwi-alloy kuluncedo ekucoceni iinkozo kunye nokuphucula ukumelana nobushushu kwe-alloy. I-carbide esetyenziswa rhoqo enesamente iqulethe inani elikhulu le-WC kunye ne-TiC, ngoko ke ubunzima, ukumelana nokuguguleka kunye nokumelana Ukumelana nobushushu kuphezulu kunokwentsimbi yesixhobo, ubunzima kubushushu begumbi buyi-89 ~ 94HRA, kwaye ukumelana nobushushu buyi-80 ~ 1000 degrees.
