Nickel-chromium and nickel-chromium-iron alloys are a group of alloys with stable physical properties, good mechanical properties at high temperatures, good cold deformation plasticity, good weldability, no brittle fracture during long-term use, and long service life. It is mostly used to manufacture heating elements with an working temperature below 1000 °C.
