Nickel-copper Alloy N05500
K500 (Monel K500, UNS N05500), a precipitation-hardening nickel-copper alloy, boasts a core highlight: building upon the excellent corrosion resistance of Monel 400, it achieves a performance leap through composition optimization and process upgrades, making it suitable for harsh working conditions in multiple fields. Specific highlights include: 1. Significantly higher strength and hardness than the basic model: Compared to Monel 400, it incorporates aluminum and titanium elements. After aging hardening, it precipitates dispersed Ni₃ (Al, Ti) phases, resulting in a yield strength approximately three times that of the basic model and a tensile strength approximately twice as high. After aging, the tensile strength can reach 1100 MPa, meeting the requirements of high-load components. Furthermore, it exhibits stable performance at high temperatures, maintaining high tensile strength up to 650℃, and can be used to manufacture turbine blades for aero-engines below 750℃.
2. **Adaptable to a Wide Range of Harsh Media:** Retaining the corrosion resistance advantages of Monel 400, it exhibits excellent resistance to corrosion in seawater, salt spray, acid and alkali solutions, and hydrogen sulfide. It also resists chloride stress corrosion cracking with an extremely low corrosion rate, ensuring long-term stable operation in applications ranging from pump shafts in flowing seawater to corrosive pipelines in petrochemical plants.
3. **Stable Performance and Non-Magnetic Properties Across a Wide Temperature Range:** It boasts exceptional low-temperature adaptability, maintaining non-magnetic properties and good toughness and ductility even at -135℃, eliminating the risk of brittle fracture. Furthermore, its stable microstructure during long-term use prevents performance degradation due to repeated temperature fluctuations, making it suitable for applications requiring high magnetic and temperature stability, such as aerospace cryogenic components and precision electronics.
4. **Highly Adaptable to Processing and Diverse Forms:** It possesses excellent cold and hot working and welding properties. Performance can be further enhanced through cold working, and post-weld treatment ensures the weld's properties are consistent with the base material. The products can be processed into various forms such as plates, bars, forgings, and wires. We can also customize and manufacture parts for different working conditions, such as pump shafts, oil well drill rings, marine fasteners, and papermaking scraper blades.
