The 3J58 Ni-Span C-902 Alloy Bar is a nickel-based alloy designed for stable watch and clock mechanisms. Known for its constant elastic modulus and low temperature coefficient, it ensures stable performance across -60°C to +100°C. Processed through solution treatment for formability and aging treatment for strength, this bar offers excellent corrosion resistance against acids and moisture, making it ideal for precision timekeeping applications. With a low thermal expansion coefficient (10–12 × 10⁻⁶/°C), density of ~8.1 g/cm³, and electrical resistivity of ~1.0 μΩ·m, it’s perfect for watchmaking.
We provide 3J58 alloy bars in various sizes and can customize compositions to meet your specific requirements, ensuring they’re ready for your timekeeping projects.
