  The core applications of nickel-based alloys can be summarized as: providing excellent mechanical properties and chemical stability in high-temperature, corrosive environments, and precision industries.
  High-temperature mechanical strength
  Aerospace: Used in aircraft engines, gas turbine blades, and other high-temperature components, maintaining high strength in environments above 540℃, such as Inconel series alloys.
  Energy Industry: Gas turbines and nuclear reactor heat exchangers rely on their resistance to high-temperature oxidation and sulfidation.
  Fields with high corrosion resistance requirements
  Chemical and Petrochemical:
  Monel alloys (such as Monel 400) are used to handle sulfuric acid, seawater, and fluorinated gases, suitable for pumps, valves, and pipelines.
  Alloy 625 resists pitting corrosion in chloride-containing environments and is used in petrochemical pipelines.
  Marine Engineering: Seawater desalination equipment and ship components utilize their seawater corrosion resistance.
  Precision and Electronics Industry
  Electronic Components: Used in electron tubes, battery casings, and wire frames, relying on their stability and corrosion resistance.
  Shape Memory Alloys: Used in medical devices (such as heart stents), smart devices, and other special functional scenarios.
  Other Special Applications
  Medical Devices: Such as nickel-titanium alloy (Nitinol) used in orthopedic implants and minimally invasive surgical tools.
  Nuclear Industry: High-temperature alloys resist radiation and corrosion in nuclear fuel processing systems.
  As seen from the above classifications, the applications of nickel-based alloys are extensive and highly specialized, with their core value lying in simultaneously meeting the demands of extreme temperatures, corrosive environments, and precision performance.
