Monel K500 Copper Alloy Wire - High-Strength Alloy Wire for Springs and Fasteners is a precipitation-hardened nickel-copper alloy wire offering significantly greater strength and hardness than Monel 400, while retaining excellent resistance to seawater, acids, and alkaline environments. It provides excellent corrosion resistance and long-term mechanical integrity, even under high load, pressure, or stress conditions.
The alloy is particularly suited for spring manufacturing, fastener production, and high-strength retaining components in marine, oil & gas, and chemical processing systems, where both corrosion resistance and mechanical performance are critical.
High strength and hardness through age-hardening (precipitation treatment)
Maintains corrosion resistance in seawater, acids, and chemical media
Excellent fatigue, wear, and stress-corrosion cracking resistance
Suitable for cold working and forming into custom spring geometries
Available in round wire format, annealed or aged upon request
Valve springs, snap rings, and spring washers for offshore oil equipment
Fasteners, bolts, and studs in seawater or chemical environments
Suspension wires and locking pins in marine and industrial equipment
High-strength electrical contacts and spring-loaded connectors
Downhole and underwater pump components requiring elasticity and resistance
Compliant with ASTM B865 / UNS N05500 / AMS 4676
Typical composition: Ni ~63%, Cu ~30%, Al ~2.7%, Ti ~0.6%
RoHS / REACH / ISO9001 certified production
100% inspected for tensile strength, microstructure, and corrosion resistance
COA, MTC, and optional third-party test reports available
