E lua vaega autu o Nitinol.
Muamua, ua taʻua o le "SuperElastic", o loʻo faʻaalia i ni faʻalavelave faʻafuaseʻi e mafai ona toe faʻaleleia ma le kink teteʻe.
O le vaega lona lua, "Shape Memory" alloys, e fa'atauaina mo le mafai e le Nitinol ona toe fa'afo'i se foliga na muai seti.
pe a vevela i luga aʻe o lona suiga temprature. O le vaega muamua e masani ona faʻaaogaina mo faʻamaʻi (faʻamau, uaea, ma isi)
ma matatioata. O le SZNK e faia ni mea e manatua ai foliga, lea e sili ona aoga mo tagata faʻamalosi,
fa'aaogaina i le tele o masini masini eseese.
