O le leo tapuni sela e mitiia ma le leo poloka Aluminum Foam
1. mea kemisi.
Aluminium foam panel: 97% alumini paʻu, 3% foaming sui, 1% TiH2
Faʻateleina le viscose, 2% Ca.O latou o le puipuiga o le siosiomaga elemene e leai se faʻaleagaina.
| Pepa fa'amaumauga o galuega (Alumini mama) | |||
| Malosi(g/cm³) | Malosi fa'amalosi(Mpa) | Malosi punou(Mpa) | Malosi'aga(KJ/M³) |
| 0.25~0.30 | 3.0~4.0 | 3.0~5.0 | 1000~2000 |

2. Uiga eletise o meafaitino.
O le conductivity o mea alumini foam e sili atu ona laʻititi nai lo le mea alumini mautu.
O le faʻafefeteina o le alumini foam e sili atu ona laʻititi nai lo le alumini malo, e tusa ma le 0.1 - 0.2 taimi ole alumini malo.
E le gata i lea, o le alumini foam e iai foi le malosi, e le mu, e le faigofie ona faʻamaʻiina, e le faigofie ona maua le matua, lelei le tau,lelei toe faʻaleleia ma toe faʻafouina uiga.
Lelei lelei le talipupuni electromagnetic: pe a o'o ile 2.6-18GHZ ole galu ole eletise,
e mafai ona oʻo i le 60-90dB le talipupuni eletise eletise ole foam alumini.
3. Corrosive uiga meafaitino.
Tete'e a'e: i le gataifale e fa'aalia le si'osi'omaga o le ea mo le tausaga, leai se fa'alavelave fa'afuase'i:
faʻavaveina tulaga pala, o le vai masima spray suʻesuʻega 2 tausaga e aunoa ma se tuusaunoaga. Faʻaalia o le faʻafefeteina o le alumini foam e lelei tele.
Ina ia faʻapipiʻi togafitiga i luga o le anti-corrosion, faʻaleleia atili le teteʻe o le corrosion.
4.Acoustic uiga.
20-40dB
5. Vibration uiga.
Malosi o le absorption o le malosi o le aafiaga, malosi malosi e mafai ona oʻo atu i le sili atu i le 50%, o le tulaga o le malosi malosi o le 80% i le 90%, e mafai ona avea ma se faʻaoga lelei o le malosi i fafo, faʻaitiitia le aʻafiaga o le faʻaleagaina.
Foam alumini damping e masani lava ona faatatau i lona absorption lelei o le teʻi po o le malosi malosi. O le fa'ate'ia o le te'i po'o le tete'e i a'afiaga e taua tele i le felauaiga o ta'avale. Foam alumini e sili atu nai lo isi foam mea e faʻafefe ai le malosi o le malosi, o le isotropic i le faʻatinoga, o le mea sili ona lelei.
Ole maualuga ole fa'aogaina o le fa'atinoga ma le a'afiaga ole malosi ole fa'aaogāina ole malosi ole malosi ole alumini u'amea 5-10 taimi.
Aluminium foam ma le porosity o le 50% e mafai ona mitiia sili atu nai lo le 2.5MJ/M3C o le malosi pe a iai se fesuiaiga o le 84%.
