O le meafaitino NiCr8020 faʻatasi ai ma le numera meafaitino 2.4869 e faʻaaogaina i foliga o fasipepa, pepa, paipa ma uaea mo vaega faufale o le ogaumu ma uaea faʻavevela.

O se u'amea fa'avevela nickel-chromium mo le vevela o le fa'agaioiga e o'o atu i le 1150 °C ma e masani ona iai ni fa'aopoopoga o eleele seasea mo se tete'e maualuga atu i le fa'ama'i oona, aemaise lava i galuega fesuia'i soo po'o suiga tetele o le vevela.

O le tete'e atu i le 'ele'ele i le ea i le 20 °C e maualuga e o'o atu i le vevela maualuga o lo'o fa'agaoioia ai, o le tete'e atu i le ea ma isi kasa o lo'o i ai le okesene fa'apea fo'i ma kasa e maualalo le okesene o lo'o i ai le naitorosene e maualuga fo'i, ae e maualalo i kasa e fa'a'okesaita ai fa'apea fo'i ma kasa e fa'aitiitia ai le okesene o lo'o i ai le sulfur.

E maualuga le tete'e atu i le fa'akāponi. Fa'aaogā mo ogaumu eletise fa'apisinisi, ogaumu enamelling, masini fa'aoga fale, ma mea fa'avevela mo le teuina o mea i le pō.
