0.12*300mm Fecral Alloy 1cr13al4 Resistor Heating Foil for Etching resistance
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.
