The 3J22 Co40CrNiMo Alloy Bar is a cobalt-based alloy designed for high-strength elastic structural parts. Its unique composition—cobalt, chromium, nickel, and molybdenum—provides superelasticity, high strength, and excellent corrosion resistance. Processed through cold-drawing and heat treatment, this bar offers a high strength-to-weight ratio and performs reliably from -60°C to +250°C. 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 mechanical applications.
We provide 3J22 alloy bars in various sizes and can customize compositions to meet your specific requirements, ensuring they’re ready for your high-strength structural projects.
