Product Description
Monel K500 nickel alloy wire, also known as UNS N05500, is a precipitation-hardenable nickel copper alloy renowned for its outstanding combination of high strength, excellent corrosion resistance, and superior fatigue endurance. Designed specifically for demanding applications in the oil and gas sector, this alloy wire maintains its integrity in corrosive environments, including saltwater exposure and acidic conditions. Unlike standard nickel alloys, Monel K500 provides enhanced mechanical properties through age-hardening, making it a preferred choice for high-performance components such as valve stems, marine fasteners, and chemical processing equipment. Sourced from reliable suppliers in regions like the USA, Europe, and Asia-Pacific, our Monel K500 wire meets international standards like ASTM B865, ensuring global compliance for oilfield operations, offshore drilling, and petrochemical plants.
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.
