Product Description

China Hot sale high quality kovar 4J29 hot forging rod

Kovar Forging Rod (ASTM F15) is controlled expansion alloy. 29% Nickel, 17% Cobalt and the remaining balance is Iron. The expansion characteristics of Kovar match both borosilicate glass and alumina ceramics, making it one of the most popular of the controlled expansion alloys for hermetic sealing applications.

Kovar Forging Rod is often referred to as a glass sealing alloy in production processing. Because its coefficient of expansion is similar to that of glass. Kovar has been used to make hermetic seals with harder Pyrex and ceramic materials. In integrated circuits, it is used in planar packages and dual in-line packages. This alloy has a wide range of applications in power tubes, microwave tubes, transistors and diodes.
