Alkrothal 720 No.1 JRho an'ny frein resistor
Ny fampiharana mahazatra ho an'ny Alkrothal 720 dia amin'ny rheostats, resistors braking, sns. Izy io koa dia ampiasaina ho singa fanafanana elektrika amin'ny fampiharana indostrialy.
Alkrothal 720 dia ferritic vy-chromium-aluminium firaka (FeCrAl alloy) ampiasaina amin'ny mari-pana hatramin'ny 1000 ° C (1830 ° F).
