Lolu hlobo lwe-alloy lubizwa ngokuthi i-YG uhlobo lwe-alloy.Isakhiwo esivamile se-WC-Co ingxubevange emhlophe iyingxubevange yezigaba ezimbili eyakhiwe isigaba se-polygonal WC kanye nesigaba se-bonding Co. Ngezinye izikhathi ngaphansi kuka-2% kwezinye (i-tantalum, i-niobium, i-chromium, i-vanadium)ama-carbideszengezwa njengezithasiselo ku-blade yokusika noma ukufa komdwebo ukuze kwandiswe impilo yesevisi yethuluzi.Kodwa-ke, lokhu akushintshi ukusebenza okuyisisekelo kwe-alloy, futhi kusengokwenhlobo ye-WC-Co ye-carbide enosimende.Uma kuqhathaniswa namanye ama-carbide anosimende anokuqukethwe okufanayo kwe-cobalt, lolu hlobo lwe-alloy lunamandla aphakeme kakhulu aguquguqukayo, amandla okucindezela, ukuqina komthelela kanye ne-elastic modulus, kanye ne-coefficient encane yomugqa wokwandisa.
Ngokuvumelana nei-tungsten carbideokusanhlamvu, lolu hlobo lwe-carbide enosimende luvame ukuhlukaniswa ngezigaba ezintathu: okusanhlamvu okuqinile, okusanhlamvu okuphakathi kanye nokusanhlamvu okuhle.Ngokuthuthukiswa kwezinto ezicutshungulwayo kanyei-carbide enosimendeizinqubo zokukhiqiza, izinhlamvu ze-WC ze-WC-Co alloys zithuthuke kakhulu ngasekugcineni okumahhadlahhadla nokuhle kakhulu.
