Advantages of nichrome

— It can not be oxidized at a long-term exploitation;
— It has a high lasting-quality;
— Heating element, that is made of this alloy, can stand thousands of on/off switching before it will be destructed;
— It has a low coefficient of a thermal expansion.

— A high real resistance;
— Excessive resistance against a formation of an oxide, a thermal fatigue and a scale at a temperature of 1200 ºС;
— A high thermal cycling firmness;


It is used for kilns, high-temperature furnaces, resistor elements, industrial tubular heating elements and heaters.
