Cov khoom siv hlau alloy yog ua los ntawm carbide (hu ua nyuaj theem) thiab hlau (hu ua binder theem) nrog siab hardness thiab melting point los ntawm hmoov metallurgy. Nyob rau hauv cov ntaub ntawv alloy carbide feem ntau siv muaj WC, TiC, TaC, NbC, thiab lwm yam., feem ntau siv binders yog Co, titanium carbide-raws li binder yog Mo, Ni.
Lub cev thiab txhua yam khoom ntawm cov khoom siv alloy yog nyob ntawm qhov muaj pes tsawg leeg ntawm cov hlau, lub thickness ntawm cov hmoov thiab cov txheej txheem sintering ntawm cov hlau. Cov theem nyuaj nrog siab hardness thiab siab melting point, qhov siab dua qhov hardness thiab kub hardness hardness ntawm cov cuab yeej alloy Qhov ntau lub binder, lub zog ntau dua. Qhov sib ntxiv ntawm TaC thiab NbC rau cov hlau yog qhov zoo los ua kom cov nplej thiab txhim kho cov cua sov ntawm cov hlau. Feem ntau siv cemented carbide muaj ntau ntawm WC thiab TiC, yog li lub hardness, hnav tsis kam thiab tsis kam Lub tshav kub tsis kam yog siab dua li ntawm cov cuab yeej steel, hardness ntawm chav tsev kub yog 89 ~ 94HRA, thiab tshav kub kuj yog 80 ~ 1000 degrees.
