Product Description

Kovar 4J29 Nickel Alloy


The Kovar nickel alloy supplied by XINHUA has similar linear expansion coefficient with borosilicate (or Pyrex) over a range of temperatures (20℃~450℃), enabling it to be compatible with the thermal expansion characteristics of hard glass so as to achieve hermetic seals.


Oxidation film densification allows this iron-nickel-cobalt alloy to be readily welded and excellent plasticity makes it fabricable. Wide applications are power tubes, vacuum tubes, transmitting tubes, kinescopes, switch tubes, transistors, relay housing, etc.
