The S3J47 Superelastic Alloy Bar is a nickel-based alloy designed for high-performance elastic elements. Its composition provides superelasticity, high strength, and excellent corrosion resistance, performing reliably from -60°C to +150°C. Processed through cold-drawing and heat treatment, this bar offers a high strength-to-weight ratio and exceptional fatigue resistance. With a low thermal expansion coefficient (10–12 × 10⁻⁶/°C), density of ~8.2 g/cm³, and electrical resistivity of ~1.0 μΩ·m, it’s ideal for demanding elastic applications.
We provide S3J47 alloy bars in various sizes and can customize compositions to meet your specific requirements, ensuring they’re ready for your elastic element projects.
