Hoʻohana nui ʻia i ka hana ʻana i nā mea kemika a me nā mea hao.Hoʻohana ʻia nā alloys alakaʻi e like me nā bearings, movable gula, solder a pēlā aku.ʻO nā poloka kepau he mau metala palupalu a palupalu, a he metala kaumaha kekahi.Hiki ke ʻoki ʻia me ka pahi, ʻo ke alakaʻi he metala kaumaha keʻokeʻo keʻokeʻo me ka uliuli, ʻo ka helu hoʻoheheʻe ʻana he 327.502 °C, ʻo 1740 °C ka paila ʻana, ʻo 11.3437 g / cm³ ka nui, ʻo ka paʻakikī he 1.5, ʻano palupalu, ikaika tensile liʻiliʻi, a me ke kumu kūʻai haʻahaʻa, no laila, hoʻohana mau ʻia ka poloka alakaʻi / alakaʻi i ke kaupaona ʻana.

He mea koʻikoʻi ke alakaʻi no ka mea e hoʻokaʻawale ana i ka radiation ionizing pōʻino, no laila, hoʻohana ʻia nā pōhaku kepau i ka ʻoihana nuklea, lāʻau lapaʻau a me ka ʻenekinia e like me nā mea pale pale no nā paia 50mm a me 100 mm manoanoa e pale aku i ka radiation ionizing.ʻO nā pōhaku keʻokeʻo he mau pōhaku ʻehā ʻehā me nā hiki ke hoʻopili.Hoʻohana nui ʻia ia i ka hana ʻana i nā pā pale ma nā wahi a i ʻole nā ​​​​kaʻina hana i kahi kiʻekiʻe loa o ka radiation.

ʻO nā pōhaku lepo keʻokeʻo kahi hoʻonā kūpono no nā kūlana pale no ka manawa lōʻihi a paʻa paha.He mea maʻalahi ka hoʻopaʻa ʻana, wehe a hoʻihoʻi hou i nā pōhaku alakaʻi no ka pale ʻoi loa.Hana ʻia nā pōhaku lepo me ke kēpau kiʻekiʻe loa, he paʻakikī maʻamau, a paʻa a paheʻe ka ʻili, e hiki ai ke hoʻokomo pono ʻia ma nā kihi ʻākau ʻoi.Hāʻawi lākou i ka pale mai ka radiation radioactive i loko o ka hale hana a me ke kaiapuni hana (wall assembly).ʻO ka hoʻopili ʻana i nā poloka alakaʻi e maʻalahi ke kūkulu, hoʻololi a kau hou i nā paia pale a me nā keʻena pale o kēlā me kēia nui.
