Application:
Resistance wire: Ni-chromium wire is used to make resistance wire and is used in heating elements such as heaters, stoves, water heaters, etc.
Thermocouple: Nickel chromium wire is the key material for manufacturing thermocouples, which are used to measure temperature, such as industrial heating processes, chemical production, etc.
Wires and Cables: Due to its good electrical conductivity and corrosion resistance, nickel-chromium wire is also used in the manufacture of wires and cables for various electrical applications.
Heat-resistant alloys: Nickel-chromium wire is also used to make heat-resistant alloys for applications in high-temperature environments such as aerospace, engine parts, and high-temperature processing equipment.
Chemical equipment: Due to its corrosion resistance, nickel-chromium wire is also widely used in chemical equipment, such as pipelines, reactors, storage tanks, etc.
