  • Available in hot rolled and polished form, with dimensions like 12*37*300mm.
  • Can undergo annealing for stress relief or stabilization processes for enhanced performance.
  • Surface treatments include sandblasting, polishing, or pickling for improved durability.
Faqs:
  • What is the primary advantage of using Invar 36 alloy?
    Invar 36 alloy is renowned for its uniquely low coefficient of thermal expansion, making it ideal for applications requiring high dimensional stability across temperature changes.
  • What are the typical applications of Bright 4J36 Hot Rolled Polished Flat Invar Bar?
    This alloy is commonly used in precision instruments, clocks, seismic creep gauges, television shadow-mask frames, valves in motors, and antimagnetic watches due to its stability and anti-corrosion properties.
  • How is the Invar 36 alloy treated for stress relief?
    The alloy can be annealed for stress relief by heating to 530-550℃ and holding for 1-2 hours, followed by cooling. For stabilization, it is heated to 830℃ in protective media, held for 20 minutes to 1 hour, and then quenched.
