Drift bead o se ituaiga o polo gaogao lele e mafai ona opeopea i luga o le vai.E efuefu pa'epa'e le lanu, e manifinifi ma 'ō'ō puipui, ma e mama tele le mamafa.O le mamafa o le iunite e 720kg/m3 (mamafa), 418.8kg/m3 (malamalama), ma le lapopoa o le vaega e tusa ma le 0.1mm.O le pito i luga e tapuni ma lamolemole, faʻatasi ai ma le maualalo o le vevela ma le afi faʻafefe o ≥ 1610 ℃.O se mea e sili ona lelei e taofia ai le vevela, faʻaaogaina lautele i le gaosiga o mea mama mama ma suauʻu viliina.O le vailaʻau vailaʻau o loʻo faʻafefeteina e masani lava ona aofia ai le silicon dioxide ma le alumini oxide, o loʻo i ai uiga eseese e pei o le lapopoʻa lelei, gaogao, mamafa mama, malosi maualuga, faʻaofuofu teteʻe, maualuga le vevela teteʻe, insulation ma mumu.O loʻo faʻaaogaina lautele e fai ma mea mata i totonu o le alamanuia refractory.

1. Mea fa'a'ese'ese fa'amumu;E pei o piliki fa'amama mama, piliki mama e le'i mu, fa'alava fa'afefete, atigi fa'aluma paipa, pa'u fa'amumu, pa'u fa'amama, pa'u fa'amamago tu'ufa'atasi, fa'amama mama fa'alava fa'alavalava.

2. Mea faufale;Teuga fa'ata'ita'i, mea fa'apipi'i auala maualuluga, fa'asusu le taualuga ma fa'a'ese'ese fa'alavalava, inisinia auala, asphalt fa'aleleia, ma isi.

3. Alamanuia suau'u;Suau'u sima, paipa anti-corrosion ma insulation, fanua suau'u i lalo o le sami, masini faaopeopea, palapala fa'aitiitia sui mo suau'u vaieliina, suauu ma kesi laina paipa, ma isi itu.

4. Mea e fa'amama ai;Fa'atumu fa'ato'aga palasitika, insulators maualuga-vevela ma maualuga, ma isi,

5. Alamanuia fa'apipi'i;Vali, vaitusi, faʻapipiʻi, vali faʻamalosi, vali faʻafefe, vali faʻafefe, vali fola, vali maualuga ma le afi, vali puipui totonu ma fafo, vali faʻafefe, vali fola, putty taʻavale, pefu atomika, ma isi;

6. Atina'e o le vateatea ma le vateatea;Satelite, roketi, va'a va'alele luga mea tu'ufa'atasia, satelite puipui puipui afi, mea o le gataifale, va'a, va'a loloto o le sami, ma isi;

7. Alamanuia palasitika;E pei o mea tau ta'avale, meafaifa'aili, mea fa'aoga fale, fa'afiafia, failauga, fa'apotopotoga moli, fa'ameamea, mea fa'aoga, vaega fa'avae, sipi, paipa, ipu, ma isi.

8. O oloa fiberglass: oloa fiberglass eseese, maamora faafoliga, vaa fiberglass, mea taulima, ma isi;

9. Mea faʻapipiʻi: mea faʻamaufaʻailoga transformer, mea faʻapipiʻi eletise, ma isi;

10. Metallurgy powder: ua faia foam e ala i le faʻafefiloi alumini, magnesium ma isi uʻamea mama.Pe a faʻatusatusa i le matrix alloy, o lenei mea tuʻufaʻatasia o loʻo i ai uiga o le maualalo o le mamafa, maualuga le malosi faʻapitoa, maualuga maualuga, faʻaleleia lelei ma le faʻaogaina o le ofuina.
