Heat Resistance: Operating temp up to 1250°C (furnace air temp), melting point 1500°C, ideal for extreme industrial environments.
0Cr25Al5 Flat Resistance Strip – High-Performance Heating Alloy Solution
Key Features
1. Superior High-Temperature Performance
- Heat Resistance: Operating temp up to 1250°C (furnace air temp), melting point 1500°C, ideal for extreme industrial environments.
- Extended Lifespan: 2–4× longer service life than Ni-Cr alloys at the same temperature, thanks to dense Al₂O₃ oxide layer with exceptional oxidation and sulfur corrosion resistance.
- High Surface Load: Supports 1.0–1.5 W/cm² (varies by temperature), enabling rapid heating and material savings.
2. Optimized Physical & Electrical Properties
- High Resistivity (1.42 μΩ·m at 20°C) with low temperature coefficient ensures stable power output.
- Lightweight: Density 7.10 g/cm³, 10% lighter than Ni-Cr alloys, reducing installation costs.
- Cost-Effective: Nickel-free composition cuts costs by >30% vs. Ni-Cr alternatives.
3. Rigorous Manufacturing Standards
- Made from virgin materials (no recycled content), RoHS-compliant with ultra-low hazardous elements.
- Customizable: Thickness (0.8–4mm), width (6–150mm), wave/special shapes supported.
Applications
Industrial
Heat treatment furnaces, metallurgical annealing lines, glass/ceramic kilns, petrochemical heating.
Consumer Appliances
Ovens, heating tubes, HVAC systems, household heaters.
Harsh Environments
Sulfur-rich atmospheres (e.g., oil refining), outperforming Ni-Cr alloys in corrosion resistance.
Installation & Usage
Critical Steps
- Fix with ceramic insulators and shields to isolate from insulation, preventing arcing.
- Maintain ≥40mm interlayer spacing for thermal expansion; handle gently to avoid brittle fracture.
Environmental Limits
- Avoid ammonia/chlorine atmospheres.
- Ensure full welding to terminals-partial welds cause arcing damage.
