Cov khoom siv cuab yeej ua los ntawm cov hlau alloy yog ua los ntawm carbide (hu ua theem nyuaj) thiab hlau (hu ua theem binder) uas muaj qhov nyuaj siab thiab yaj los ntawm hmoov metallurgy. Qhov twg cov khoom siv cuab yeej ua los ntawm cov hlau alloy carbide feem ntau siv yog WC, TiC, TaC, NbC, thiab lwm yam. Cov khoom siv sib txuas feem ntau yog Co, cov khoom sib txuas raws li titanium carbide yog Mo, Ni.
Cov khoom siv lub cev thiab cov khoom siv kho tshuab ntawm cov khoom siv alloy nyob ntawm seb cov khoom sib xyaw ua ke, qhov tuab ntawm cov hmoov me me thiab cov txheej txheem sintering ntawm cov alloy. Cov theem nyuaj dua nrog qhov nyuaj siab thiab qhov chaw yaj siab, qhov nyuaj dua thiab qhov kub siab ntawm cov cuab yeej alloy Qhov ntau dua cov binder, qhov muaj zog dua. Kev ntxiv TaC thiab NbC rau cov alloy yog qhov zoo rau kev ua kom cov nplej thiab txhim kho qhov kub tsis kam ntawm cov alloy. Cov cemented carbide feem ntau siv muaj ntau ntawm WC thiab TiC, yog li qhov nyuaj, hnav tsis kam thiab tiv taus Qhov kub tsis kam yog siab dua li cov hlau cuab yeej, qhov nyuaj ntawm chav tsev kub yog 89 ~ 94HRA, thiab qhov kub tsis kam yog 80 ~ 1000 degrees.
