    Tk-4J50 (Expansion alloy)

    (Common Name: 50H, N50, Vacovit 500, FeNi50)
    4J50 alloy is mainly composed of iron, nickel elements. It is characterized with a fixed coefficient of expansion. Increase the thermal expansion coefficient and the Curie point with increase of nickel content.
    4J50 alloy is widely used the structure of the sealing material in the electric vacuum industry.
