Alkrothal a-nuas 720 No.1 jrAirson revistor breic
Tha tagraidhean àbhaisteach airson Alkrothal 720 ann an reostats, resistors breiceadh, msaa. Tha e cuideachd air a chleachdadh mar eileamaidean teasachaidh dealain ann an tagraidhean gnìomhachais.
Tha Alkrothal 720 na alloy iarann-chromium-alùmanum ferritic (Alloy FeCrAl) airson a chleachdadh aig teòthachd suas gu 1000 ° C (1830 ° F).

Chaidh a chleachdadh gu mòr mar fhrithealadh breic brosnachail agus àirneis teasachaidh fùirneis.
Tha nas lugha de neart teth aige na aloidhean Tophet ach puing leaghaidh mòran nas àirde.
