Cemented Carbide ke phofo metallurgy sehlahisoa sintered ho tloha boima bo phahameng, refractory tšepe motsoako phofo (joaloka WC, TiC, TaC, NbC le tse ling tse phahameng mocheso carbides) le tšepe binder (Co, Mo, Ni, joalo-joalo).Kaha sebopeho sa Cemented Carbide se na le palo e kholo ea li-carbide tse nang le ntlha e phahameng ea ho qhibiliha, boima bo phahameng le botsitso bo botle ba lik'hemik'hale, ho thatafala, ho hanyetsa le ho hanyetsa mocheso oa Cemented Carbide li phahame haholo.Ho thatafala ha mocheso oa kamore ea Cemented Carbide ka kakaretso ke 89 ~ 93HRA, e lekanang le 78 ~ 82HRC, 'me mocheso o lumelletsoeng oa ho itšeha o phahame ho 800 ℃ ~ 1000 ℃, mme boima ba eona bo ntse bo le 77 ~ 85HRA le ho 540 ℃, eo e lekana le boima ba mocheso oa kamore ea tšepe ea lebelo le phahameng.
Ka hona, ts'ebetso ea ho itšeha ea Cemented Carbide e phahame haholo ho feta ea HSS, tlas'a ts'ebetso e ts'oanang, lebelo la ho itšeha la Cemented Carbide le lumelloa ho ba makhetlo a 4 ho isa ho makhetlo a 10 ho feta a HSS, 'me lebelo la ho itšeha le ka fihla ho feta. 100m/min, 'me e ka khaola mefuta eohle ea thepa e thata ho ea mochini, joalo ka tšepe e thata, e ke keng ea khaoloa ke lisebelisoa tsa ho itšeha tsa HSS.Leha ho le joalo, ka lebaka la matla a eona a tlase a ho kobeha (hoo e ka bang 1/2 ~ 1/4 ea HSS), ho tiea ha tšusumetso (hoo e ka bang (1/8 ~ 1/30) ea HSS) le ts'ebetso e mpe, ka hona, hajoale, lisebelisoa tsa Cemented Carbide li teng. haholo-holo e sebelisoang ho hlahisa lisebelisoa tse sa khaotseng tsa ho itšeha le ho sebetsa ka mokhoa o bonolo oa bohale 'me ha ho na tšusumetso.Ha li-carbide tse ka har'a carbide e entsoeng ka samente li phahame, ho thatafala ho phahame, empa matla a flexural a batla a le tlaase;ha litaba tsa binder li phahame, matla a flexural a phahame 'me boima bo tlaase.ISO e tla aroloa ka P, K le M mekhahlelo e meraro ea carbide e entsoeng ka samente, karolo e kholo ea likarolo tse tharo tsa carbide e entsoeng ka samente ke WC, e tsejoang ka hore ke WC-based cemented carbide.
K sehlopha se lekana le tungsten-cobalt samente carbide ea China, lebitso la khoutu YG, haholo-holo e entsoeng ka WC le Co.
Mofuta oa YG oa matla a ho kobeha a carbide le matla a ts'usumetso a betere, a loketse ts'ebetso ea lisebelisoa tse brittle, a ka sebelisoa bakeng sa tšepe e entsoeng ka tšepe, litšepe tse se nang ferrous le li-alloys tsa tsona le lisebelisoa tse se nang tšepe.YG mofuta oa carbide e entsoeng ka samente le keketseho ea cobalt dikahare, boima ba eona bo fokotseha, ha matla a ho kobeha a ntse a eketseha, bokhoni ba ho mamella tšusumetso ea ntlafatso ea mahlahahlaha, e loketseng ho sebetsa ka thata.Ho fapana le hoo, ho thatafala, ho apara ho hanyetsa le ho hanyetsa mocheso ho eketseha, ho loketse ho qeta.

Mofuta oa YT oa carbide e entsoeng ka samente hangata e ka sebelisoa bakeng sa ho itšeha ka lebelo le phahameng la tšepe.
M class e lekana le tungsten-titanium-tantalum (niobium) cobalt cemented carbide ea China, sehlopha sa codenamed YW, se eketsoang litaba tse itseng tsa TaC kapa NbC sebopeho sa carbide e samente e kaholimo ho ntlafatsa boima ba mocheso o phahameng, matla a mocheso o phahameng le ho hanyetsa abrasion ea thepa e entsoeng ka samente ea carbide.
