Mipando ya Tungsten carbide ndi Mavavu amayikidwa mumafuta osiyanasiyana osungidwa ndi gasi, mavavu akumunda wamafuta, mafakitale amafuta a malasha. Munthawi yanthawi yayitali komanso yovuta yogwira ntchito, valavu ya tungsten carbide ndiyo yabwino kwambiri. Panthawi imodzimodziyo, valavu ya tungsten carbide ndi mpando uli ndi ubwino wotsatira: phokoso lochepa komanso kukana kwambiri kuvala; mkulu kuuma, mkulu compressive mphamvu; Kukhazikika kwamankhwala abwino komanso kulimba kwamphamvu kochepa; Coefficient yowonjezera yotsika; kuchititsa kutentha ndi kuchititsa magetsi.
