Advantages of eurofecral
— a high real resistance, mechanical strength;
— an increased resistance against an oxide formation, a thermal fatigue, an oxide scale at a temperature of 1200ºС;
— a great corrosive resistance on air, in a vacuum and oxidizing environments;
The main field of use: in kilns, resistor elements, high-temperature furnaces, industrial tubular heating elements and heaters.

Operating life
Cr23Al5T is an ideal alloy with an excessive specific real resistance (1,20−1,30 Ohm-mm2/m) which combine a heat resistance up to 1450 °C. It 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 a very high relative density (7,2 g/cm3), but it has a great flow limit.
