O le paʻu alumini o se mea e sili ona mama, faʻapipiʻi lelei e faia mai le alumini oxide (Al2O3) lea e faʻaaogaina lautele i le tele o mea tau pisinisi.O se pa'epa'e tioata pa'epa'e e masani ona gaosia e ala i le fa'amamaina o le oa o le bauxite.O le paʻu alumina o loʻo i ai le tele o mea e manaʻomia, e aofia ai le maualuga o le maʻaʻa, teteʻe vailaʻau, ma le faʻaogaina o le eletise, lea e avea ai ma mea taua i le tele o pisinisi.

Alumini Oxide Pa'u Fa'aaogāga
1.Ceramic Alamanuia: ceramics faaeletonika, ceramics refractory, ma ceramics faʻatekinisi faʻapitoa.
2.Polishing ma Abrasive Alamanuia: tioata mata, semiconductor wafers, ma luga metallic.
3. Catalysis
4. Thermal Spray Coatings: aerospace ma fale gaosi oloa.
5. Insulation eletise
6.Refractory Alamanuia: ogaumu linings, ona o lona tulaga liusuavai maualuga ma sili ona mautu vevela.
7. Faʻaopoopo i Polymers
8.Other: e pei o se faʻapipiʻi malosi, adsorbents, catalysts ma catalyst lagolago, faʻapipiʻi gaogao, mea tioata faʻapitoa, mea faʻapipiʻi, resin filler, bio-ceramics etc.
