Ko te kāpira tungsten (te tauira matū: WC) he matū (ina koa, he kāpira) kei roto ngā wāhanga ōrite o ngā ngota tungsten me ngā ngota waro. I tōna āhua taketake, he paura hina pai te kāpira tungsten, engari ka taea te pēhi me te hanga hei āhua mā te tukanga e kiia nei ko te sintering hei whakamahi i roto i ngā mīhini ahumahi, ngā taputapu tapahi, ngā mea whakakoi, ngā anga wero pukupuku me ngā whakapaipai. He momo here kobalt me ​​te nikara te momo here o te kāpira tungsten.

E rua pea te pakari o te karawiti tungsten i te maitai, ko te modulus Young kei te 530–700 GPa (77,000 ki te 102,000 ksi), ā, e rua te matotoru o te maitai—tata ki waenganui i te mata me te koura.

He tino kaha te tungsten carbide mō tētahi rauemi tino mārō, tino pakari hoki. He teitei ake te kaha pēhi i te nuinga o ngā konganuku me ngā koranu rewa, whakarewa, hanga rānei.
