ʻO ke koho ʻana i ka mea kūpono no kāu mau lau hiki ke alakaʻi pinepine i ka huikau. ʻO ka hopena, aia ke kī i ka hana i manaʻo ʻia a me nā ʻano koʻikoʻi i loaʻa iā ia. ʻO ka manaʻo o kēia ʻatikala ma luna o Tungsten, kahi mea i hoʻohana nui ʻia, e nānā ana i kāna mau hiʻohiʻona, nā noi, a me ka pono maʻamau o nā lau tungsten.
Ma ka papa periodic, paʻa ka tungsten i ke kūlana 74th. Ke kūlana nei ma waena o nā metala ikaika loa o ka Honua, ua kaena ʻo ia i ka helu heheʻe nui loa ma waena o nā metala āpau, a hiki i kahi mahana o 3,422°C!
Hiki i kona palupalu ke ʻoki me kahi hacksaw wale nō, e alakaʻi ana i ka hoʻohana pinepine ʻana o Tungsten ma ke ʻano he alloy. Hoʻohui ʻia me nā metala like ʻole e hoʻohana i kā lākou mau hiʻohiʻona kino a me ke kemika. Hāʻawi ʻo Alloying Tungsten i nā pono ma ke ʻano o ka pale ʻana i ka wela a me ka paʻakikī, ʻoiai e hoʻonui ana i kona hoʻohana ʻana a me ka hoʻohana ʻana ma kahi ākea ākea o ka hoʻohana. Hoʻonohonoho ʻia ʻo Tungsten Carbide e like me ka alloy Tungsten nui. ʻO kēia pūhui, i hana ʻia e ka hui ʻana i ka pauka Tungsten a me ka pauka Carbon, e hōʻike ana i ka helu paʻakikī o 9.0 ma ka pālākiō Mohs, e like me ka pae paʻakikī o ke daimana. Eia kekahi, ʻoi aku ka kiʻekiʻe o ka helu hoʻoheheʻe o ka Tungsten Carbide alloy, a hiki i 2200 ° C. No laila, ʻoi aku ka maikaʻi o ka hoʻohana ʻana o Tungsten Carbide ma mua o Tungsten i kona ʻano ʻano ʻole, ma muli o kāna mau ʻano Tungsten a me nā pono hou o Carbon.
ʻO Tungsten Carbide blade, ʻike ʻia no kona kūpaʻa kūʻokoʻa i ka wela a me nā ʻōpala a me kona ʻano lōʻihi, hoʻohana nui ʻia i nā mea ʻoki ʻoihana e like me nā pahi mīkini. Ua hoʻohana ka ʻoihana i ka pahi Tungsten Carbide no kahi kokoke i hoʻokahi haneli mau makahiki. I kēia manawa, hoʻohana pinepine ʻia ka ʻili Tungsten Carbide e hoʻohālikelike a ʻokiʻoki. I kēia hihia, ua koho ʻia ʻo Tungsten Carbide i mea kūpono a maikaʻi loa. ʻO ka paʻa a me ka hiki ke kū i ka lole e hiki ai iā ia ke ʻoki i nā ʻano paʻakikī i nā manawa he nui me ka loaʻa ʻole o kahi pōʻino.
Ma keʻano laulā, loaʻa i nā lau o ka tungsten carbide ka nui o nā noi ma nā kahua he nui, ʻoi loa no ka mīkini paʻakikī a me nā ʻāpana kiʻekiʻe.
