1cr13al4 Electric Resistance Wire Iron Chrome Aluminum Resistor Heating Strip
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.
