Kovar® Alloy Applications
(Also known as ASTM F15, NILO® K, Pernifer® 2918, Rodar®, and Dilvar® P1)
The expansion characteristics of Kovar match both borosilicate (Pyrex) glasses and alumina ceramics. Making it one of the most popular of the controlled expansion alloys for hermetic sealing applications, Kovar allows direct mechanical connections over a range of temperatures in conductors entering glass envelopes of electronic parts.
Products that have utilized the special properties of Kovar:
- Hybrid Packages
- Microwave Tubes
- Power Tubes
- Vacuum Tubes (valves)
- X-ray Tubes
