The 3J22 High-Durability Elastic Alloy Tube is a cobalt-based alloy designed for harsh environment tubing. Its composition—cobalt, chromium, nickel, and molybdenum—provides superelasticity, high strength, and excellent corrosion resistance, performing reliably from -60°C to +250°C. Processed through cold-drawing and heat treatment, this tube offers a high strength-to-weight ratio and outstanding fatigue resistance. With a low thermal expansion coefficient (10–12 × 10⁻⁶/°C), density of ~8.3 g/cm³, and electrical resistivity of ~1.0 μΩ·m, it’s ideal for demanding applications.
We provide 3J22 alloy tubes in various sizes and wall thicknesses, with customizable compositions to meet your specific requirements, ensuring they’re ready for your harsh environment projects.
| Grades | Density (g/cm³) | Electrical Resistivity (10⁻⁶ Ω·cm) | Thermal Conductivity (W/m·K) | Modulus of Elasticity (GPa) | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation at Break (%) | Elastic Limit (MPa) | Fatigue Life (cycles) | Working Temperature Range (°C) | Temperature Coefficient |
| 8.1 | 80 | 11 | 144 | 800 | 1000 | 10 | 800 | >10⁷ | -60 to 200 | Extremely low temperature coefficient of elasticity | |
| 8.3 | 120 | 40 | 125 | 300 | 600 | 20 | 300 | >10⁷ | -40 to 150 | Elasticity remains constant with minimal temperature sensitivity | |
| 8.2 | 100 | 15 | 180 | 1100 | 1400 | 5 | 1100 | >10⁶ | -200 to 500 | Maintains high strength even at elevated temperatures |
