The 3J22 Co40CrNiMo Alloy Tube is a cobalt-based alloy designed for high-strength elastic applications. Its composition—cobalt, chromium, nickel, and molybdenum—provides superelasticity, exceptional 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 high-strength 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 elastic projects.
