0Cr13Al4 is a high-performance ferritic stainless steel heating alloy wire designed for high-temperature and oxidation-resistant applications.
With a composition of 13% chromium (Cr) and 4% aluminum (Al), combined with ultra-low carbon content (≤0.08%), this alloy delivers exceptional corrosion resistance, thermal stability, and efficient electrothermal conversion, making it ideal for industrial heating systems, household appliances, and specialized electrical components.
Superior High-Temperature Performance
Aluminum forms a dense Al₂O₃ oxide layer at high temperatures, enabling oxidation resistance up to 800°C and prolonged durability.
Chromium enhances baseline corrosion resistance for harsh environments.
Efficient Electrothermal Properties
Optimal resistivity ensures uniform heat generation and high energy conversion efficiency.
Excellent high-temperature strength and creep resistance extend component lifespan.
Cost-Effective Processing
Ferritic structure supports both cold and hot working, suitable for wire drawing, coiling, and forming.
More economical than nickel-chromium alloys (e.g., Cr20Ni80) while maintaining performance.
Environmental Adaptability
Resists corrosion in freshwater, atmospheric conditions, and mild acidic/alkaline environments.
Ferromagnetic properties make it compatible with electromagnetic induction heating systems.
Industrial Heating Components
Heating elements for high-temperature furnaces, molten metal heaters, and heat treatment equipment.
Chemical pipeline tracing and reactor heating systems.
Household Appliances
Heating wires for electric kettles, ovens, and space heaters.
Heating elements in electric blankets and portable warmers.
Automotive & Machinery
Automotive exhaust sensor heaters and diesel engine glow plugs.
High-temperature protective components in mechanical systems.
⚠️ Precautions
High aluminum content may reduce low-temperature toughness; avoid mechanical shock.
Prolonged use above 800°C may accelerate oxidation; protective coatings are recommended.
Customized non-standard material; confirm compliance with GB/T 1234 or in-house specifications before procurement.
? Processing Recommendations
Coiling/Welding: Perform under inert gas shielding to prevent oxidation.
Surface Treatment: Pre-oxidation improves the density of the Al₂O₃ protective layer.
Cost Efficiency
Balances performance and affordability, replacing premium nickel-based alloys.
Rapid Thermal Response
Low heat capacity ensures quick and precise temperature control.
Customization
Available in diameters (0.1mm-5mm), hardness levels, and resistivity adjustments.
