Na waiwai o ka Beryllium metala

ʻO ka Beryllium he kila hina, māmā (ʻo 1.848 g / cm3 ka nui), paʻakikī, a maʻalahi ka hanaʻana i kahi papa pale pale oxide ma kaʻili i ka lewa, no laila ua paʻa i ka mahana wela.ʻO ka Beryllium kahi helu heheʻe o 1285 ° C, ʻoi aku ka kiʻekiʻe ma mua o nā metala māmā ʻē aʻe (magnesium, aluminika).No laila, he māmā, paʻakikī, a kūpaʻa nā ʻāpana beryllium i nā wela kiʻekiʻe, a he mau mea kūpono no ka hana ʻana i nā mea lele a me nā lako aerospace.ʻO kahi laʻana, hiki i ka hoʻohana ʻana i ka beryllium alloys e hana i nā pahu rocket hiki ke hoʻemi nui i ke kaumaha;ka hoʻohana ʻana i ka beryllium alloys e hana i nā satelite artificial a me nā mokulele mokulele hiki ke hōʻoia i ka palekana o ka lele.

ʻO ka pilikia maʻamau o nā metala maʻamau ʻo "Fatigue".No ka laʻana, e uhaʻi ʻia kahi kaula uea hoʻokau lōʻihi ma muli o ka "māluhiluhi", a e nalowale ka punawai i kona elasticity ma muli o ka "māluhiluhi" inā e hoʻopili pinepine ʻia a hoʻomaha.He hana anti-fatigue ka beryllium metala.No ka laʻana, e hoʻohui i 1% metala beryllium i ke kila hoʻoheheʻe.ʻO ka pūnāwai i hana ʻia me kēia kila kila hiki ke hoʻolōʻihi i 14 miliona mau manawa me ka ʻole o ka nalowale ʻana o ka elasticity ma muli o ka " luhi ", ʻoiai ma ke ʻano o ka "wela ʻulaʻula" Me ka ʻole o ka nalowale ʻana o kona maʻalahi, hiki ke wehewehe ʻia he "indomitable".Inā hoʻohui ʻia ma kahi o 2% metala beryllium i ke keleawe, ʻaʻole ʻokoʻa ka ikaika tensile a me ka elasticity o kēia keleawe beryllium alloy mai ke kila.No laila, ʻike ʻia ka beryllium ʻo ka "metala paʻa luhi".

ʻO kekahi hiʻohiʻona koʻikoʻi o ka beryllium metala ʻaʻole ia e ʻā i ka wā e pa ai, no laila, hoʻohana pinepine ʻia nā ʻāpana keleawe-nickel i loaʻa i ka beryllium no ka hana ʻana i nā drills "non-fire", nā hamare, nā pahi a me nā mea hana ʻē aʻe, i hoʻohana kūikawā ʻia no ka hana ʻana. nā mea puhi a pahū.

Loaʻa i ka beryllium metala ka waiwai o ke akaka i ka radiation.ʻO ka lawe ʻana i nā kukui X ma ke ʻano he laʻana, ʻo ka hiki ke komo i ka beryllium he 20 mau manawa ʻoi aku ka ikaika ma mua o ke alakaʻi a he 16 mau manawa ʻoi aku ka ikaika ma mua o ke keleawe.No laila, ʻo ka beryllium metala ka inoa o ka "aniani metala", a hoʻohana pinepine ʻia ka beryllium e hana i "nā puka makani" o nā paipu X-ray.

He hana maikaʻi nō hoʻi ka beryllium metala no ka hoʻouna ʻana i ke kani.ʻO ka wikiwiki hoʻolaha o ke kani i ka beryllium metala he kiʻekiʻe e like me 12,600 m / s, ʻoi aku ka kiʻekiʻe ma mua o ka wikiwiki o ke kani i ka ea (340 m / s), ka wai (1500 m / s) a me ke kila (5200 m / s) .makemake ʻia e ka ʻoihana mea kani.
