Fecral 0Cr13Al4 Resistor ribbon
1. Description
FeCrAl Resistance Alloy belongs to electric heating alloy. FeCrAl alloy contains a large number of chromium and aluminum elements, it has excellent high temperature oxidation resistance, its temperature can reach 1400 degrees Celsius.
2. Advantage
FeCrAl Heating alloy has also joined the rare earth elements, changing the composition of the oxide film, the organizational structure and improving the strength and ductility of the oxide film, the increase in density and adhesion, thereby enhancing the antioxidant capacity of the alloy, extended heating element life.
3. Forming
It exists in the form of strip, round wire, ribbon wire, sheet, tape, rod and plate.
4. Application
They are mainly used in electric locomotive, diesel locomotive, metro vehicle and high speed moving car etc brake system brake resistor, electric ceramic cooktop, industrial furnace.
