ʻO ke kila Tungsten: Aia ka huahana i hoʻopau ʻia ma kahi o 18% tungsten alloy steel. ʻO ke kila Tungsten ka mea paʻa paʻa, ʻike ʻia ʻo tungsten-titanium alloy. ʻO 10K Vickers ka paʻakikī, ʻelua wale nō i ke daimana. Ma muli o kēia, ʻo nā huahana kila tungsten (nā wati kila tungsten maʻamau) loaʻa ke ʻano o ka maʻalahi ʻole. Hoʻohana pinepine ʻia i nā mea lathe, nā ʻāpana drill hopena, nā ʻoki ʻoki aniani, nā ʻoki tile. He ikaika a ʻaʻole makaʻu i ka annealing, akā palupalu.
ʻO ka carbide i hoʻopaʻa ʻia: no ke kahua o ka pauka metallurgy. ʻO ka carbide Cemented, i ʻike ʻia he metala ceramic, he seramika me kekahi mau waiwai o ke metala, i hana ʻia me nā carbide metala (WC, TaC, TiC, NbC, etc.) a i ʻole nā mea metala (e like me Al2O3, ZrO2, etc.) e like me nā mea nui, a me ka nui kūpono o ka pauka metala (Co, Cr, Molur, Ni, Fe, etc.) Hoʻohana ʻia ʻo Cobalt (Co) e pāʻani i kahi hopena paʻa i loko o ka alloy, ʻo ia hoʻi, i ka wā o ka sintering, hiki iā ia ke hoʻopuni i ka pauka tungsten carbide (WC) a hoʻopaʻa paʻa pū. Ma hope o ka hoʻoluʻu ʻana, lilo ia i carbide sima. (Ua like ka hopena me ka sima i loko o ke koneki). ʻO ka maʻiʻo maʻamau: 3% -30%. ʻO Tungsten carbide (WC) ka mea nui e hoʻoholo ai i kekahi mau mea metala o kēia carbide cemented a i ʻole cermet, e helu ana no 70% -97% o ka huina o nā ʻāpana (ke kaumaha ratio). Hoʻohana nui ʻia ia i nā ʻāpana a i ʻole nā pahi a me nā poʻo mea hana ma nā wahi hana koʻikoʻi.
No ke kila tungsten i ka carbide i hoʻopaʻa ʻia, akā ʻaʻole pono ke kila tungsten. I kēia mau lā, makemake nā mea kūʻai aku ma Taiwan a me ʻAsia Hema e hoʻohana i ka huaʻōlelo tungsten steel. Inā ʻoe e kamaʻilio kikoʻī iā lākou, e ʻike ʻoe i ka hapa nui o lākou e pili ana i ka carbide cemented.
ʻO ka ʻokoʻa ma waena o ka tungsten steel a me ka cemented carbide ʻo ia ka tungsten steel, i ʻike ʻia ʻo ke kila kiʻekiʻe a i ʻole ke kila mea hana, i hana ʻia ma ka hoʻohui ʻana i ka hao tungsten e like me ka tungsten raw material i ke kila hoʻoheheʻe ʻia me ka hoʻohana ʻana i ka ʻenehana steelmaking, ʻike ʻia hoʻi me ke kila kiʻekiʻe a i ʻole ke kila kila, a ʻo kona ʻano tungsten maʻamau he 15-25%; ʻoiai ua hana ʻia ka carbide cemented e ka sintering tungsten carbide e like me ke kino nui me ka cobalt a i ʻole nā mea hoʻopaʻa ʻē aʻe e hoʻohana ana i ka ʻenehana metallurgy pauka, a ʻoi aku ka nui o kāna ʻike tungsten ma luna o 80%. ʻO ka mea maʻalahi, ʻo nā mea āpau me ka paʻakikī ma mua o HRC65 e like me ka lōʻihi e hiki ke kapa ʻia he carbide cemented, a ʻo ke kila tungsten wale nō ke ʻano o ka carbide cemented me ka paʻakikī ma waena o HRC85 a me 92, a hoʻohana pinepine ʻia e hana i nā pahi.
