    FeNi Nickel Iron Alloy Precision 0.5mm Invar 36 Wire For Sealing Precision Instrument

    FeNi Nickel Iron alloy precision 0.5mm Invar 36 Wire for Sealing Precision Instrument


    INVAR 36 is a nickel-iron, low expansion alloy containing 36% nickel. It maintains nearly constant Dimensions Over the range of normal atmospheric temperatures, and has a low coefficient of expansion from cryogenic temperatures to about 500° F. The alloy also retains good strength and toughness at cryogenic temperatures.

    INVAR 36 can be hot and cold formed and machined using processes similar to

    austenitic stainless steels. INVAR 36 is weldable using Filler Metal CF36 which is

    available in bare wire for both the GTAW and GMAW process.

    The heat treatment process
    Annealing for stress reliefHeated to 530~550ºC and hold 1~2 h. Cold down
    annealingIn order to eliminate hardening, which be bring out in cold-rolled, cold drawing process. Annealing needs heated to 830~880ºC in vacuum,hold 30 min.
    The stabilization process
    In protective media and heated to 830 ºC, hold 20min. ~ 1h, quench
    Due to the stress generated by quenching, heated to 315ºC,hold 1~4h.

    Precautions

    Can not be hardened by heat treatment
    Surface treatment can be sandblasting, polishing or pickling.
    Alloy can be used 25% hydrochloric acid pickling solution at 70 ºC to clear oxidized surface
