Good Thermal Conductivity AMS 7726B Kovar Plate UNS K94610
Kovar Plate is an iron-cobalt-nickel alloy with a coefficient of thermal expansion similar to that of hard glass. Because Kewa alloys are tough and versatile, extensive quality control is applied in the manufacturing of UNS K94610 alloys to ensure consistent physical and mechanical properties, making stretching, stamping and machining easier. In addition, Kovar, it is the most dynamic mechanical property.
Product Advantages of Kovar Plate
Expansion alloy Kovar is precisely formulated and controlled to produce a coefficient of thermal expansion that is very close to that of hard glass or ceramic, meaning that it expands and contracts at a similar rate. It is therefore perfect in applications where it is used in conjunction with glass or ceramic materials, especially where a hermetic seal must be maintained across a wide temperature range. Other key Kovar benefits include:
- Extremely low coefficient of thermal expansion (CTE)
- Metal stamping capabilities
- Advanced dimensional stability
