Description

Nickel-Iron-Cobalt Alloy UNS K94610 4J29 Kovar Rod

Kovar Rod is a low expansion metal of iron nickel cobalt melted in vacuum. The chemical composition of Kova is controlled within a narrow range to ensure that the accurate uniform thermal expansion performance is continuously maintained. The Kova manufacturing process utilizes high-end quality control to ensure uniform physical and mechanical properties for deep drawing, stamping and CNC processing.

Product advantages of Kovar Rod

The expansion alloy Kovar is precisely formulated and controlled so that its coefficient of thermal expansion is very close to that of hard glass or ceramic, meaning that it expands and contracts at similar rates. As such, it is well suited for applications where it is used in combination with glass or ceramic materials, especially where an airtight seal must be maintained over a wide temperature range. Kovar's other key strengths include:

  • Very low coefficient of thermal expansion (CTE)
  • Metal stamping capacity
  • Advanced dimensional stability

Application of Kovar Rod

It is used to make iron nickel cobalt alloy strips, bars, plates and pipes matched with hard glass for sealing. Suitable for transmitting tube, oscillating tube, pilot tube, transistor, sealed plug, relay shell and other electric vacuum devices. It has a certain linear expansion coefficient in the temperature range of 20 ℃ - 450 ℃, and can match with hard glass to seal firmly.
