Tungsten carbide (cov mis tshuaj: WC) yog ib qho tshuaj sib xyaw (tshwj xeeb, carbide) uas muaj cov khoom sib npaug ntawm tungsten thiab carbon atoms. Hauv nws daim ntawv yooj yim tshaj plaws, tungsten carbide yog ib qho hmoov grey zoo, tab sis nws tuaj yeem raug nias thiab tsim ua cov duab los ntawm cov txheej txheem hu ua sintering rau kev siv hauv cov tshuab kev lag luam, cov cuab yeej txiav, cov khoom siv abrasives, cov plhaub armor-piercing thiab cov hniav nyiaj hniav kub. Tungsten carbide muaj cov hom cobalt thiab nickel binder.

Tungsten carbide yog kwv yees li ob npaug ntawm cov hlau, nrog rau Young's modulus ntawm kwv yees li 530–700 GPa (77,000 txog 102,000 ksi), thiab yog ob npaug ntawm qhov ceev ntawm cov hlau - yuav luag nruab nrab ntawm cov hlau lead thiab kub.

Tungsten carbide muaj lub zog siab heev rau cov khoom siv uas tawv thiab nruj heev. Lub zog compressive yog siab dua li txhua yam hlau yaj thiab cam khwb cia lossis forged thiab alloys.
