Product Description
0Cr21Al6Nb FeCrAl Heating Wire is a high-performance iron-chromium-aluminum alloy heating wire, made from high-purity FeCrAl alloy with niobium addition, integrating excellence in high-temperature resistance, oxidation resistance, and high resistivity. As an efficient heating element material, it provides stable performance in extreme environments, with a maximum continuous operating temperature of 1350°C, widely used in industrial furnaces and household appliances for efficient heating and long-life applications.
Max Continuous Service Temperature: 1350°C Melting Point: 1510°C Surface: Bright or Oxidized Condition: Annealed
High electrical resistivity: Converts electrical energy into heat in resistance-heating element designs.
FeCrAl alloy: The iron-chromium-aluminum composition is used for high-temperature resistance heating applications.
Oxidation resistance at elevated temperatures: Performance depends on operating atmosphere, element design and service cycle.
Niobium-containing grade: 0Cr21Al6Nb is specified separately from other FeCrAl grades; confirm the grade and chemistry on the order documents.
Temperature-dependent application limits: The listed 1350°C maximum continuous service temperature must be evaluated with wire size, surface load, installation and furnace conditions.

FAQ
The current product information lists a maximum continuous service temperature of 1350°C for the heating element. This figure depends on the element design and operating conditions; it should not be treated as a guaranteed wire temperature for every installation.
A typical reference value is 1.45 ± 0.07 μΩ·m at 20°C. Confirm the applicable resistivity requirement and test method for the material being quoted.
Available diameters and tolerances depend on current production capability and order quantity. Send your required size for confirmation.
Suitability depends on the specific atmosphere, temperature and operating cycle. Do not assume general resistance to acids, alkalis, chlorides or sulfur-bearing gases. Provide the process atmosphere for review.
Please state the required certificate or inspection report in your inquiry. Available documentation will be confirmed for the specific grade and order.
