Product Description
Monel K500 Bright Wire (UNS N05500) is an advanced nickel-copper alloy wire that delivers superior performance compared to standard Monel 400. Through controlled additions of aluminum and titanium followed by age-hardening heat treatment, it achieves approximately three times the yield strength and double the tensile strength of Monel 400 while maintaining excellent ductility and toughness.
The bright, polished finish provides a smooth, clean surface ideal for medical and high-precision components. This wire remains non-magnetic even at low temperatures, exhibits outstanding resistance to seawater, acids, alkalis, and chloride-induced stress corrosion cracking, and retains its mechanical properties across a wide temperature range (from cryogenic conditions up to approximately 480°C / 896°F).
Available in various diameters, our Monel K500 polished bright wire is manufactured to the highest standards, ensuring consistency, reliability, and compliance with stringent industry requirements for medical and specialty applications.
High Strength & Hardness: Age-hardenable for significantly higher tensile strength (up to 1100+ MPa) and yield strength compared to Monel 400.
Bright Polished Finish: Smooth, reflective surface for reduced friction, improved cleanliness, and aesthetic/functional precision in medical devices.
Excellent Corrosion Resistance: Superior performance in marine, chemical, acidic, and chloride environments; highly resistant to pitting and stress corrosion cracking.
Non-Magnetic Properties: Low magnetic permeability, even at sub-zero temperatures, making it suitable for sensitive electronic and medical equipment.
Wide Temperature Performance: Maintains strength and ductility from cryogenic levels up to elevated temperatures.
Good Fatigue Resistance: Ideal for dynamic loading applications such as springs and fasteners.
High Ductility & Toughness: Remains workable and tough even after strengthening treatments.

FAQ
A: Monel K500 Bright Wire is a precipitation-hardenable nickel-copper alloy wire (UNS N05500) with enhanced strength from aluminum and titanium additions. It features a bright, polished surface and offers superior corrosion resistance combined with high mechanical strength, making it ideal for medical and demanding industrial uses.
A: Monel K500 provides much higher strength and hardness through age-hardening, while maintaining similar excellent corrosion resistance. It is non-magnetic down to very low temperatures, unlike some conditions of Monel 400.
A: Yes. Its high strength, polished finish, corrosion resistance, and non-magnetic properties make it excellent for medical devices, surgical tools, springs, and components requiring precision and biocompatibility in harsh environments.
A: The polished bright surface reduces friction, improves cleanliness, enhances corrosion resistance on the surface, and provides a professional appearance suitable for visible or precision medical and electronic parts.
A: It performs well from cryogenic temperatures (down to -100°C or lower while remaining non-magnetic) up to approximately 480°C (896°F), retaining strength and ductility.
