ASTM F15 Low Coefficient Of Thermal Expansion Kovar Alloy Plate 4J29

ASTM F15 Low Coefficient Of Thermal Expansion 4J29 Plate

kovar Alloy Plate is an iron cobalt nickel alloy with a coefficient of thermal expansion like that of hard glass. Since Kovar Alloy is tough and versatile, while employing extensive quality controls throughout UNS K94610 alloy’s manufacturing process to ensure uniform physical and mechanical properties for ease in deep drawing, stamping and machining are consistently achieved. Furthermore, the coefficient of thermal expansion (CTE) of Kovar is its most dynamic mechanical property.

Advantages of kovar Alloy Plate

The expansion alloy kovar Alloy Plate is precisely formulated and controlled so that its coefficient of thermal expansion is very close to that of hard glass or ceramic, meaning that it expands and contracts at similar rates. As such, it is well suited for applications where it is used in combination with glass or ceramic materials, especially where an airtight seal must be maintained over a wide temperature range. Kovar's other key strengths include:

• Very low coefficient of thermal expansion (CTE)
• Metal stamping capacity
• Advanced dimensional stability

Application of 4J29 Plate

Used for making iron, nickel and cobalt alloy bars, bars, plates, pipes with hard glass seal. It is suitable for electric vacuum device such as transmitting tube, oscillation tube, conduit, transistor, sealing plug and relay shell. In the temperature range of 20℃ -450 ℃ has a certain linear expansion coefficient, can be matched with hard glass, sealed firmly.
