Hoʻohana ʻia nā noho karbida Tungsten a me nā ʻūhā i loko o nā ʻano aila a me ke kinoea i waiho ʻia, nā kīwaha ʻaila, nā ʻoihana kemika. I ke kūlana o ka wā hana lōʻihi a paʻakikī, ʻo ka valve tungsten carbide ka koho maikaʻi loa. I ka manawa like, loaʻa i ka valve tungsten carbide a me ka noho nā mea maikaʻi aʻe: haʻahaʻa haʻahaʻa a me ke kiʻekiʻe o ka lole pale; kiʻekiʻe paʻakikī, kiʻekiʻe compressive ikaika; Paʻa kemika maikaʻi a me ka paʻakikī haʻahaʻa; ka hoonui haahaa; ka lawe ʻana i ka wela a me ka lawe ʻana i ka uila.
