Alkrothal 14 ferritic ironchromiumuminium alloy (FeCrAl alloy)
Alkrothal 14 (Resistance heat wire ma resistance wire) Alkrothal 14 o se ferritic ironchromiumuminium alloy (FeCrAl alloy) faʻatasi ai ma le maualuga o le resistivity talafeagai mo le faʻaogaina i le vevela e oʻo atu i le 1100 ° C (2010 ° F). Alkrothal 14 e masani ona fa'aoga mo uaea fa'atete'e eletise mo fa'aoga e pei o uaea fa'avevela.
