Hoʻohui ʻia ka pahu alumini i loko o ka pauka alumini maʻemaʻe ma hope o ke kaʻina hana hū, a loaʻa iā ia nā ʻano metala a me nā hiʻohiʻona. Loaʻa iā ia ka haʻahaʻa haʻahaʻa, ka haʻalulu haʻalulu kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ahi ikaika, ka pale ʻana i ka corrosion, ka hoʻohaʻahaʻa leo a me ka hoʻohaʻahaʻa leo, haʻahaʻa haʻahaʻa thermal conductivity, kiʻekiʻe electromagnetic pale, ikaika kū i ka wā, kānana hiki, hana maʻalahi, hoʻonohonoho maʻalahi, hana kiʻekiʻe. pololei a me ka uhi ili.

Pono:
1. Māmā māmā: ʻO ka Density he 0.1-0.4 mau manawa o ka alumini metala.
2. 'Oolea kiko'ī ki'eki'e: He 1.5 manawa ko ke kila kona kulou ana.
3. High damping a haʻalulu ikehu absorption: ʻO ka hana hoʻoheheʻe ʻana he 5-10 mau manawa e like me ka alumini metala. Ke loaʻa i ka alumini foam me ka porosity o 84% he 50% mau ʻano like ʻole, hiki iā ia ke komo ma mua o 2.5MJ/m3 ikehu.
4. Hana maikaʻi acoustic:
(1) Ka hoʻokō ʻana i ke kani ʻana (ke kelepona paʻa): I ka wā o ke kani alapine ma waena o 800HZ a me 4000HZ, ʻoi aku ka nui o ka hoʻoheheʻe kani ʻana o ka pahu alumini paʻa paʻa ma mua o 0.9.
(2) Nā waiwai hoʻoheheʻe leo (micro through-hole a ma waena o ka lua): I ka manawa o ke kani alapine ma waena o 125HZ-4000HZ, ʻoi aku ka nui o ka hoʻoheheʻe kani ʻana o ka alumini foamed a hiki i ka 0.8, a ʻoi aku ka nui o ka coefficient absorption o ka octave. 0.4.
5. ʻO ka hana pale electromagnetic maikaʻi loa: I ka manawa o ka hawewe electromagnetic ma waena o 2.6GHZ a me 18GHZ, hiki i ka mana pale electromagnetic o ka pahu alumini ke hiki i 60dB a 90dB.
6. ʻO nā waiwai wela maikaʻi: Paʻa ka pahu pahu me ka porosity o 80-90%, e like me ke kinikini. He maikaʻi ka hoʻoheheʻe ʻana o ka wela ma lalo o nā kūlana convection ikaika ma muli o kona mau pores pili.
7. ʻAʻole ia e wela a maikaʻi ke kūpaʻa wela. ʻO ka pale ʻana i ka corrosion, maikaʻi ke kūpaʻa ʻana i ka wā, ka haʻahaʻa haʻahaʻa haʻahaʻa, ʻaʻole ʻelemakule, ʻaʻohe mea ʻawaʻawa.
8. Maʻalahi e hana: maʻalahi e ʻoki, wili a me ka sima; hiki ke hoʻopaʻa ʻia e like me ke ʻano i makemake ʻia ma ke kālai ʻana; ka hoʻomaʻamaʻa ʻana i ka ʻili me ka pena organik a i ʻole ka pena kino; ʻili ʻelua ʻaoʻao, e hana ana i kahi māmā nui, papa kiʻekiʻe-rigidity.
9. E hoʻouka maʻalahi: Hiki ke hoʻokomoʻia ka pahu alumini ma nā wahi kiʻekiʻe me kaʻole o nā mea hoʻokiʻekiʻe mechanical, e like me ke kaupaku, nā paia a me nā kaupaku, a me nā mea'ē aʻe, hiki ke hoʻopili ponoʻia a hoʻopaʻaʻia me nā wili, aiʻole hiki ke hoʻopiliʻia ma nā paia a me nā kaupaku me nā mea hoʻopili.
