0Cr23Al5 resistance strip is a high-performance iron-chromium-aluminum (Fe-Cr-Al) alloy engineered for demanding electric heating applications requiring exceptional oxidation resistance, mechanical durability, and energy efficiency. With a composition of 22–25% chromium, 4.5–6.0% aluminum, and balanced iron, this alloy forms a dense, self-healing alumina (Al₂O₃) layer at temperatures up to 1,400°C (2,552°F), providing robust protection against oxidation, carburization, and sulfurization in harsh industrial environments. Its low carbon content (≤0.08%) and controlled silicon (≤1.0%) minimize embrittlement, ensuring longevity in cyclic thermal operations such as industrial furnaces, kilns, and aerospace heating systems.
Certified to GB/T 1234 and DIN 17470 standards, the 0Cr23Al5 strip delivers a tensile strength of 580–720 MPa and a surface load capacity of 2.2 W/cm², making it ideal for heating elements in air, vacuum, or inert gas atmospheres. The alloy’s high electrical resistivity (1.40 μΩ·m) and low temperature coefficient of resistance (TCR) ensure stable energy output, outperforming conventional nickel-chromium alloys in cost-effectiveness and operational lifespan under extreme conditions.

Q1: What distinguishes 0Cr23Al5 from other Fe-Cr-Al alloys like 0Cr25Al5?
A: 0Cr23Al5 offers a balanced chromium-aluminum ratio for enhanced cyclic oxidation resistance at marginally lower material costs, ideal for applications up to 1,400°C.
Q2: Can this alloy operate in chlorine-rich environments?
A: While its alumina layer resists oxidation, prolonged exposure to chlorine above 800°C may necessitate protective coatings or controlled atmospheres.
Q3: Is pre-treatment required for new 0Cr23Al5 heating elements?
A: Yes. Pre-oxidation at 900–1,050°C for 1–2 hours strengthens the protective oxide layer, extending service life by up to 30%.
