The S3J47 Superelastic Alloy Wire is a nickel-based alloy designed for high-performance elastic elements. Its superelasticity, excellent corrosion resistance, and stability across -60°C to +200°C make it ideal for dynamic components like springs and diaphragms. Processed through cold-drawing and heat treatment, this wire offers a high strength-to-weight ratio and outstanding fatigue resistance. With a low thermal expansion coefficient (10–12 × 10⁻⁶/°C), density of ~8.2 g/cm³, and electrical resistivity of ~1.0 μΩ·m, it’s perfect for demanding applications.
We offer S3J47 wire in various diameters and can customize its composition to meet your specific requirements, ensuring it’s ready for your high-performance elastic element projects.
