Fa'aoga: Niobium ma niobium alloy rods ma uaea o lo'o fa'aaogaina lautele i matata o le kemisi, eletise, va'alele ma le aerospace ona o lo latou maualuga o le liusuavai, tete'e o le pala ma le malulu lelei. Niobium ma le niobium alloy rods e faʻaaogaina e fai ma mea faʻapipiʻi ma roketi nozzles mo afi vaalele, reactor i totonu ma mea peleue, ma vaega eseese e mafai ona faʻafefeteina e tetee atu i le nitric, hydrochloric, poʻo le sulfuric acid corrosion tulaga. O le faʻaopopoina o le zirconium i le niobium e mafai ona faʻaleleia atili ai le faʻamaʻi faʻamaʻi ma le malosi o mea. Niobium ma niobium-zirconium uaea u'amea fa'aaoga lautele i le gaosiga o lamepa sodium maualuga-voltage ma anode ta'ita'ia o capacitors electrolytic.

Aisea e Filifili ai Matou:

1. E mafai ona e mauaina le mea sili ona lelei e tusa ai ma lou manaʻoga i le tau maualalo.

2. Matou te ofoina atu foʻi Reworks, FOB, CFR, CIF, ma tau tuʻuina atu i le faitotoa. Matou te fautuaina oe e fai fefaʻatauaiga mo felauaiga o le a fai si taugofie.

3. O mea matou te tuʻuina atu e mafai ona faʻamaonia atoatoa, saʻo mai le tusi faʻataʻitaʻiga suʻega mataʻutia i le faʻamatalaga pito mulimuli.

4. e faʻamautinoa e tuʻuina atu se tali i totonu ole 24 itula (masani ile itula lava e tasi)

5. E mafai ona e maua isi fa'atauga, fa'atauga fa'atau ma fa'aitiitia le taimi o gaosiga.

6. Matou te faʻamaoni atoatoa ia matou tagata faʻatau. Afai o le a le mafai ona ausia ou manaʻoga pe a uma ona suʻesuʻeina filifiliga uma, matou te le faʻasesēina oe e ala i le faia o folafolaga pepelo e faʻatupuina sootaga lelei tagata faʻatau.

Faʻamautinoaga Tulaga (e aofia uma ai le Faʻaleagaina ma le le faʻaleagaina)

1. Su'ega Fa'aaliga Vaaia

2. Su'esu'ega fa'ainisinia e pei o le tensile, Elongation ma le fa'aitiitiga ole vaega.

3. Iloiloga o aafiaga

4. Su'esu'ega su'ega vaila'au

5. Su'ega ma'a'a
