Comparison with Other Materials
Here’s how Cr30Ni70 stacks up against other common materials:
Parameter | Cr30Ni70 Nichrome | FeCrAl (Kanthal) | Copper | Stainless Steel |
|---|---|---|---|---|
Max Operating Temp (°C) | 1150 | 1400 | 200 | 800 |
Electrical Resistivity (μΩ·m) | 1.18-1.25 | 1.35-1.45 | 0.017 | 0.7-0.8 |
Corrosion Resistance | Excellent | Good | Poor | Moderate |
Tensile Strength (MPa) | 600-750 | 600-700 | 200-400 | 500-700 |
Oxidation Resistance | High | High | Low | Moderate |
Density (g/cm³) | 8.1 | 7.1 | 8.9 | 7.8 |
Cost Efficiency | High | Moderate | High | Moderate |
Chemical Processing Suitability | Excellent | Good | Limited | Moderate |
Cr30Ni70’s superior corrosion resistance and balanced resistivity make it ideal for chemical processing, outperforming copper in harsh environments and offering better durability than stainless steel. While FeCrAl can handle higher temperatures, it falls short in corrosion resistance, making our wire a better fit for chemical applications.
