What Is Kovar Alloy?
Kovar is a nickel-cobalt-iron alloy consisting of approximately 29% nickel, 17% cobalt, 54% iron, and small amounts of other elements such as manganese and silicon.
This material is often used to make parts that need to maintain dimensional stability at different temperatures, such as electronic and semiconductor components. Kovar’s low CTE is very close to the CTE of some glass-ceramics, such as borosilicate glass. This makes Kovar a popular choice for sealing applications, where it can be used to create a reliable and tight seal between glass and metal parts.
Kovar alloys are heat treated at different stages. Annealing of Kovar rods, wires, and plates is mainly to relieve stress and ensure appropriate hardness for further processing. Heat treatment of Kovar finished parts is mainly to obtain the best conditions for further electroplating, brazing or sealing.
Characteristics of Kovar
- Low thermal expansion coefficient: Kovar has a very low thermal expansion coefficient, which makes it an ideal material for applications that require high dimensional stability over a wide temperature range.
- Good machinability: Kovar is a relatively soft material, which makes it easy to machine and work with. It also enables the production of complex shapes and designs.
- High corrosion resistance: Kovar has excellent corrosion resistance, making it ideal for use in harsh environments or applications where exposure to chemicals is a concern.
- Hermetic sealing capabilities: Kovar has good hermetic sealing capabilities, which make it ideal for applications where a vacuum seal is required.
- Magnetic properties: Kovar exhibits ferromagnetic properties, which make it suitable for use in applications that require magnetic shielding.
Kovar Alloy in Healthcare
