ʻO ke koʻokoʻo tungsten alloy no ka hoʻoheheʻe ʻana i nā huahana
Hana ʻia nā ʻōpala hoʻoheheʻe make, ʻike ʻia hoʻi ʻo punch dies, mai ke kila mea hana kiʻekiʻe. ʻO nā ʻano kikoʻī o ke kila mea hana i hoʻohana ʻia no ka hoʻoheheʻe ʻana i nā molds e komo pū ana:
1. H13 mea kila: H13 mea he wela mea hana kila i maʻa mau i ka make-hoolei molds ma muli o kona maikaʻi hui 'ana o kiʻekiʻe toughness, wela ka wela a me ka lole pale. Hiki iā ia ke pale i nā wela kiʻekiʻe a me nā pōʻai wela e pili ana i ke kaʻina hana make-casting.
2. P20 Mea Paahana Steel: P20 mea maʻamau kumu mold kila maʻamau i hoʻohana 'ia ma haʻahaʻa-volume make hoolei palapala noi. Loaʻa iā ia ka machinability maikaʻi, polishability a me ke kūpaʻa dimensional.
3. D2 mea kila kila: D2 mea he kiʻekiʻe-carbon, kiʻekiʻe-chromium mea paahana kila i hoʻohana 'ia no ka make-hoole' ana i hoʻoheheʻe 'ia e pono ai kiʻekiʻe kapa komo a paakiki.
Ua koho ʻia kēia mau mea kila no ka hoʻoheheʻe ʻana i nā mold no ka mea hiki iā lākou ke kū i ke koʻikoʻi kiʻekiʻe, nā mahana a me nā pōʻai pinepine o ke kaʻina hoʻoheheʻe make ʻoiai e mālama ana i ke kūpaʻa dimensional a me ke kūpaʻa ʻana. Hoʻohui ʻia, hiki iā lākou ke mīkini ʻia a hoʻoliʻi ʻia e hana i nā ʻano paʻakikī a me nā hoʻopau ʻili maikaʻi e pono ai no ka hoʻoheheʻe make.
ʻO Tungsten he metala maʻemaʻe, ʻaʻole ia he mea hao. He metala refractory me ka helu heheʻe kiʻekiʻe loa o nā metala a pau, i mea waiwai nui i nā noi wela kiʻekiʻe. ʻIke ʻia ʻo Tungsten no kona ʻano paʻakikī, kiʻekiʻe kiʻekiʻe, a me ke kūpaʻa ʻana i ka ʻaʻahu a me ka corrosion.
ʻOiai ʻo ka tungsten ponoʻī he metala maʻemaʻe, hoʻohana pinepine ʻia ʻo ia ma ke ʻano he mea hoʻohui i ka hana ʻana o nā tungsten alloys, e like me tungsten superalloys, i hana ʻia ma ka hui ʻana i ka tungsten me nā metala ʻē aʻe e loaʻa ai nā waiwai kikoʻī.
ʻAʻole hoʻohana maʻamau ʻia ʻo Tungsten ma ke ʻano he mea hoʻoheheʻe make no ka mea ʻo kona wahi hoʻoheheʻe kiʻekiʻe a me nā waiwai ʻē aʻe e paʻakikī ai ka hoʻohana ʻana i nā ʻano hana hoʻoheheʻe kuʻuna. He wahi hehee kiʻekiʻe loa ka Tungsten o 3422°C (6192°F), ʻoi aku ka kiʻekiʻe ma mua o nā metala hoʻolei make maʻamau e like me ka aluminika, ka zinc a me ka magnesium. ʻO kēia wahi hoʻoheheʻe kiʻekiʻe e paʻakikī a paʻakikī ka hoʻohana ʻana i ka tungsten i nā kaʻina hana hoʻoheheʻe make maʻamau.
Akā, ʻoi aku ka maʻamau o ka tungsten i nā noi kahi i ʻoi aku ka maikaʻi o kona wahi hoʻoheheʻe kiʻekiʻe, paʻakikī, a me nā mea ʻē aʻe ʻē aʻe, e like me nā ʻāpana umu wela kiʻekiʻe, nā pilina uila, nā ʻāpana aerospace, a ma ke ʻano he mea hoʻohui i nā mea e like me ka tungsten carbide.
