    Kovar* (ASTM F-15)


    Kovar is a Ni-Fe alloy with 29%  Nickel, 17% Cobalt and the remaining balance is Iron. The expansion  characteristics of Kovar match both borosilicate (or Pyrex) glasses and  alumina ceramics, making it one of the most popular of the controlled  expansion alloys for hermetic sealing applications.


    Kovar alloy is magnetic at all  temperatures below the Curie point. Magnetic properties will depend upon heat  treatment; the lower the hardness, the higher the permeability values and  lower hysteresis loss.

    Density: 8.36g/cm3

    Curie Temp: 435°C(815°F)


    Kovar is widely used in applications  such as power tubes, microwave tubes, transistors, diodes, hybrid packages,  and other kinds of scientific instruments.
