ʻO ka tungsten carbide kahi hui kemika inorganic nona ka nui o nā ʻātoma tungsten a me ke kalapona. ʻO ka tungsten carbide, i ʻike ʻia hoʻi ʻo "cemented carbide", "hard alloy" a i ʻole "hardmetal", he ʻano mea metallurgic nona ka pauka tungsten carbide (kemika: WC) a me nā mea hoʻopaʻa ʻē aʻe (cobalt, nickel, etc.).

Hōʻike ka lāʻau tungsten carbide i ka paʻakikī kiʻekiʻe a me ka ikaika transverse rupture, a he hana ʻoi aku ka maikaʻi ma ke kūʻē ʻana i ka abrasion a me ka corrosion, e hiki ai ke hoʻohana nui ʻia i nā ʻoihana he nui.

E hoʻohana nui ʻia ka lima ʻōpala tungsten carbide no ke kākoʻo wili, hoʻonohonoho, anti-thrust a me ke sila o ke axle o ka motika, centrifuge, mea pale a me ka mea hoʻokaʻawale o ka pamu uila i hoʻoheheʻe ʻia i loko o nā kūlana hana maikaʻi ʻole o ka wili wikiwiki kiʻekiʻe, ka abrasion one lash a me ka corrosion kinoea i ke kahua aila, e like me ka lima ʻōpala slide, ka lima ʻōpala motika a me ka lima ʻōpala sila.

Hoʻohana ka ʻūlū carbide cemented i nā mea maka a me nā mea kōkua e like me ke kumu mua o ka tungsten carbide saturated, ka pauka cobalt ultra-fine kiʻekiʻe, ka hoʻohuihui kalapona pololei, ka wili ʻana i ka pōpō tilt, ka hoʻomaloʻo ʻana i ka vacuum, ke kaomi pololei, ka sintering degreasing digital a me ka sintering pressure personalized post-processing a me nā kaʻina hana metallurgy pauka holomua ʻē aʻe. Hoʻohana nui ʻia ka ʻūlū alloy paʻakikī i ka ʻoihana pamu kūikawā, me ke ola lawelawe lōʻihi a me ka maikaʻi hilinaʻi.

Ke hana nei nā ʻūpā umauma bearing i kahi ʻano abrasive ma muli o ka wili ʻana, ka friction, a me nā mea ʻē aʻe a me nā ʻāpana i pili i ka media.

ʻO ka ʻūlū bushing tungsten carbide me ke kūpaʻa i ka ʻaʻahu a me ka pala a me ka paʻakikī haki kiʻekiʻe no ka hoʻoikaika axial koi, a hiki ke hoʻokō i ke koi bushing pōʻino maʻamau API.
