ʻO Bucking Bars: He kōkua ikaika no ka riveting pololei

He mea spherical i hana ʻia e ka hui ʻana i ka tungsten me nā metala ʻē aʻe (e like me ka nickel, hao a keleawe paha), a loaʻa iā ia nā waiwai maikaʻi loa o ka tungsten a me kāna mau ala. Hoʻohui ka pōleʻa alloy Tungsten i ka kiʻekiʻe kiʻekiʻe a me ka paʻakikī o ka tungsten me ka machinability o nā mea hoʻohui, e hoʻohana nui ʻia i nā kula he nui. ʻO kāna mau waiwai nui he:

ʻO ka "kaumaha kikoʻī kiʻekiʻe" ʻo ia ka nui o ka ratio o ke kaumaha o ka mea i kona leo, ʻo ia hoʻi, kiʻekiʻe ka mānoanoa. Ma nā kahua like ʻole, ʻokoʻa paha nā manaʻo a me nā hoʻohana ʻana o ka "kiʻekiʻe kiʻekiʻe". Eia kekahi mau mea e pili ana i ka "kaumaha kiʻekiʻe":

1.Tungsten-ma muli kiʻekiʻe-density alloy2. Molybdenum-ma muli o ke kiʻekiʻe kiʻekiʻe3. nickel-ma muli kiʻekiʻe-density alloy4. ʻO ka hao-ma muli o ka hao

Tungsten vs. Kaumaha Lead: He aha ka ʻokoʻa?
