Kovar Alloy Applications

(Also know as ASTM F-15, NILO K, Pernifer 2918, Rodar, and Dilvar P1)

Since the expansion characteristics of Kovar match both borosilicate (or Pyrex) glasses and alumina ceramics, Kovar is one of the most popular of the controlled expansion alloys for hermetic sealing applications -- allowing direct mechanical connections over a range of temperatures in conductors entering glass envelopes of electronic parts.

Kovar alloy applications include:

Vacuum Tubes (valves)
X-ray Tubes
Microwave Tubes
Power Tubes
Light bulbs
Transistors
Diodes
Hybrid Packages
