Alkrothal 720 No.1 JRloogu talagalay iska caabinta biriiga

Codsiyada caadiga ah ee Alkrothal 720 waxay ku jiraan rheostats, resistors braking, iwm. Waxa kale oo loo isticmaalaa sida walxaha kuleylka korantada ee codsiyada warshadaha.

Alkrothal 720 waa bir-chromium-aluminium alloy (FeCrAl alloy) oo loo isticmaalo heerkulka ilaa 1000°C (1830°F).
