29HK / Kovar / Rod Fe Ni Alloy Bar With Optimal Thermal And Electrical Conductivity
|
Detailed Product Description
Product Description29HK / Kovar Plate/Rod Fe Ni alloy bar General Description Size Range:Kovar is a nominal 29%Ni-17%Co-54%Fe alloy that is a well-known glass-sealing alloy suitable for sealing to hard glasses. Kovar has a nominal expansion coefficient of approximately 5 ppm/°C and inflection temperature of ~450 °C (840 °F). Kovar (ASTM F15) has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials. This alloy has found wide application in power tubes, microwave tubes, transistors, and diodes. In integrated circuits, it has been used for the flat pack and the dual-in-line package.
