Alkrothal 720 Nu.1 JRmo taofi taofi
O talosaga masani mo Alkrothal 720 o loʻo i totonu o rheostats, braking resistors, ma isi. E faʻaaogaina foi e avea ma elemene faʻavevela eletise i mea tau pisinisi.
Alkrothal 720 o se u'amea u'amea-chromium-aluminium alloy (FeCrAl alloy) mo le fa'aoga i le vevela e o'o atu i le 1000°C (1830°F).
