Relevance:
Fecrak us an ideal alloy with an excessive specific real resistance(1.20-1.30 ohm-mm2/m)which combine a heat resistance up to 1450C and is claimed to be indispensable at temperature extremes.These properties allow using this alloy extensively while manufacturing heating units. It has a perfect corrosive resistance on air,in argon, in a vacuum, oxidizing, sulfur-containing and carboniferous environments.It shows not very high relative density(7.2g/cm3),but it has a great yield limit.
