Product Description
Monel K500, a versatile nickel-copper alloy known for its precipitation hardening capabilities, forms the core of our fatigue-resistant spring wire solutions. This advanced material combines the corrosion resistance of standard Monel alloys with enhanced strength from age-hardening processes, making it perfect for spring wire applications where repeated stress cycles could lead to failure in lesser materials. Our Monel K500 spring wire is available in various diameters and tempers, tailored for global industries including North American manufacturing hubs, European aerospace sectors, and Asian marine engineering projects. Whether you're designing valve springs, compression springs, or torsion springs, this wire delivers consistent performance, reducing downtime and maintenance costs in harsh operational settings.
Engineered to withstand millions of cycles without cracking, ideal for dynamic spring applications in vibrating machinery.
Resists pitting, crevice corrosion, and stress corrosion cracking in saltwater, acids, and alkaline environments.
Offers tensile strengths up to 160 ksi, ensuring reliable performance under heavy loads and high temperatures up to 500°F.
Suitable for sensitive electronic and medical devices where magnetic interference must be minimized.
Available from 0.005" to 0.250" diameters, with options for annealed, spring temper, or full hard conditions to match specific engineering needs.
Precipitation hardening process boosts hardness and strength without sacrificing ductility, perfect for long-term spring reliability.
