Māhele ʻO Tungsten Heavy Alloy (WNIFE).
wehewehe
He mea hoʻolako kūikawā mākou i ka hana ʻana i nā ʻāpana tungsten kaumaha.Hoʻohana mākou i nā mea maka o ka tungsten heavy alloy me ka maʻemaʻe kiʻekiʻe e hana i kā lākou mau ʻāpana.ʻO ke kiʻekiʻe wela re-crystallization kekahi o nā hiʻohiʻona koʻikoʻi no nā ʻāpana alloy kaumaha tungsten.Eia kekahi, loaʻa iā ia ka plasticity kiʻekiʻe a me ke kūpaʻa abrasive maikaʻi loa.ʻOi aku ka mahana o ka crystallization hou ma luna o 1500 ℃.ʻO nā ʻāpana koʻikoʻi koʻikoʻi tungsten e kūlike me ka maʻamau ASTM B777.
Waiwai
ʻO ka mānoanoa o nā ʻāpana paʻa koʻikoʻi tungsten he 16.7g / cm3 a hiki i 18.8g / cm3.Eia kekahi, loaʻa nā ʻāpana tungsten koʻikoʻi i nā ʻano o ke kiʻekiʻe kiʻekiʻe a me ke kūpaʻa corrosion.Loaʻa i nā ʻāpana ʻāpana koʻikoʻi ʻo Tungsten ke kūpaʻa haʻalulu maikaʻi a me ka plasticity mechanical.He haʻahaʻa haʻahaʻa haʻahaʻa hoʻonui hoʻonui ʻia nā ʻāpana tungsten koʻikoʻi, hiki ke komo i nā kukuna ikehu kiʻekiʻe.
