I-tungsten carbide (ifomula yekhemikhali: WC) yikhompawundi yekhemikhali (ngokukodwa, i-carbide) equlethe iinxalenye ezilinganayo zeeathom ze-tungsten kunye ne-carbon. Kwimo yayo esisiseko, i-tungsten carbide yimpuphu engwevu ecolekileyo, kodwa inokucinezelwa kwaye yenziwe ibe ziimo ngenkqubo ebizwa ngokuba yi-sintering ukuze isetyenziswe koomatshini bemizi-mveliso, izixhobo zokusika, izinto ezirhabaxa, amaqokobhe okubhoboza izixhobo kunye nobucwebe. I-tungsten carbide inohlobo lwe-cobalt kunye ne-nickel binder.

I-tungsten carbide iqine kabini kunentsimbi, ine-Young's modulus emalunga ne-530–700 GPa (77,000 ukuya kwi-102,000 ksi), kwaye iphindwe kabini kunentsimbi—phantse ibe phakathi kwentsimbi yentsimbi kunye negolide.

I-tungsten carbide inamandla aphezulu kakhulu kwisixhobo esiqinileyo nesiqinileyo. Amandla okucinezela aphezulu kakhulu kunazo zonke iintsimbi ezinyibilikisiweyo nezibunjiweyo okanye ezenziwe ngesinyithi kunye nee-alloys.
