    Introduction



    Alloy 46: Consisting of 46% nickel and iron balance, 46 Alloy is a controlled expansion alloy used mostly in electronic applications, especially for glass and ceramic seals. Alloy 46 is also known as Pernifer 462, NILO 464, and Glass-Seal 461. Alloy 46 is used in metal and glass seals for hermetic and electronic tubes.

    NOTES:

        1Under condition that the average coefficient of the linear expansion meets the requirements of the standard, the content of nickel, cobalt and copper are allowed to deviate from the stated range.

            2The shape and dimensions of the alloys are in compliance with GB/T14985.

    Notes:

        1. The Vickers hardness of the annealed strip (sheet) should be no more than 170.

        2. For the unannealed strip (sheet) delivered, after heat treat at 900, and then hold for 30 min, the Vickers hardness should be no more than 170.
