Tungsten carbide lulú (WC) jẹ ohun elo aise akọkọ fun iṣelọpọ titungsten carbide, kemikali agbekalẹ WC.ni kikun orukọ, tungsten carbide lulú jẹ dudu hexagonal gara, luster ti fadaka, líle ati diamond iru si awọn ti o dara adaorin ti ina ati ooru.Ojutu yo 2870 ℃, aaye gbigbọn 6000 ℃, iwuwo ibatan 15.63 (18 ℃).Tungsten carbide jẹ insoluble ninu omi, hydrochloric acid ati sulfuric acid, tiotuka ni nitric acid – hydrofluoric acid adalu acid.Tungsten carbide mimọ jẹ ẹlẹgẹ, ti o ba dapọ pẹlu iye kekere ti titanium, koluboti ati awọn irin miiran, o le dinku brittleness.Ti a lo bi ohun elo gige irintungsten carbide, nigbagbogbo fi kun titanium carbide, tantalum carbide tabi adalu wọn lati mu agbara agbara-ibẹjadi dara si.
Awọn ohun-ini kemikali ti tungsten carbide jẹ iduroṣinṣin.Tungsten carbide lulú jẹ lilo akọkọ ni iṣelọpọ ti carbide cemented.Ni tungsten carbide lulú, awọn ọta erogba ti wa ni ifibọ ninu awọn interstices ti tungsten irin lattice ati ki o ko ba awọn atilẹba irin lattice, lara ohun interstitial ojutu ri to, ki o ti wa ni tun mo bi aafo-filling (tabi fi sii) agbo.
Irisi ti tungsten carbide lulú jẹ grẹy, pẹlu ilosoke ti iwọn patiku ọja, awọ lati dudu si ina.Awọ yẹ ki o jẹ paapaa ati ni ibamu, laisi awọn ifisi oju ti o han.
