0Cr23Al5 FeCrAl resistance wire is one of the most durable and heat-resistant alloys in the FeCrAl family. With approximately 23% chromium and 5% aluminum, this alloy is designed to withstand some of the highest temperatures encountered in heating applications, performing reliably at continuous service temperatures up to 1400°C. Its combination of high resistivity, mechanical stability, and strong oxidation resistance makes it a top choice for industrial and household heating systems alike.

The performance of 0Cr23Al5 is driven by its chemistry. The high chromium content enhances resistance to scaling and corrosion, while the aluminum forms a dense and stable oxide film (Al₂O₃) that protects the wire during repeated heating and cooling cycles. Compared to lower chromium and aluminum grades like 0Cr19Al3 , this alloy offers a longer service life and better resistance under extreme conditions.
Key properties include:
-
Stable Resistivity: Provides consistent electrical resistance for precise heating control.
-
High-Temperature Performance: Can endure continuous service up to 1400°C.
-
Oxidation Resistance: Retains strength and integrity even in aggressive thermal environments.
-
Creep Resistance: Maintains mechanical stability under prolonged stress.
-
Cost Efficiency: Offers long-term savings compared to nickel-based heating alloys.
These qualities make 0Cr23Al5 a premium-grade resistance wire suitable for advanced heating technology.
