KOV (Kovar) Description :

KOV is a low thermal expansion alloy with a main composition of 29Ni-17Co-Fe.
Although the coefficient of thermal expansion is higher than that of Alloy 36 or Alloy 42, it is close tohard glass, and is therefore used for IC leadframes and other applications for sealing hard glass.

FAQ's of KOV (Kovar) - UNS K94610 | Low Thermal Expansion Alloys:

Q: How can KOV (Kovar) alloy be supplied to meet my project's requirements?

A: KOV (Kovar) is available in coil and sheet forms. The width and thickness can be customized to suit your application, so please contact us directly to discuss your precise specifications and receive tailored supply solutions.

Q: What makes Kovar suitable for hard glass encapsulant applications?

A: Kovar's specific chemical composition ensures its thermal expansion closely matches that of hard glass. This compatibility effectively reduces the risk of cracking and provides a strong, hermetic seal, making it ideal for encapsulation uses.

Q: When should I consider using KOV (Kovar) instead of other alloys?

A: You should consider Kovar when working with hard glass or ceramics in hermetic sealing applications where thermal expansion compatibility is critical, such as in vacuum tubes, electronic package housings, and sensor assemblies.

Q: Where does KOV (Kovar) primarily find its applications?

A: Kovar is widely used in industries like electronics, telecommunications, and aerospace, particularly where glass-to-metal seals are essential, such as in semiconductor packaging and electronic enclosures.

Q: What processes can Kovar undergo after purchase?

A: Depending on the application, Kovar can be further processed by machining, stamping, or welding. It is supplied in various tempers-annealed, skin passed, or as rolled-making it adaptable to different manufacturing needs.

Q: What are the benefits of choosing Kovar as an exporter, manufacturer, or supplier?

A: Kovar's low thermal expansion, reliability in hermetic sealing, and customizable supply options make it a dependable choice for global exporters, manufacturers, and suppliers catering to high-tech and precision industries.
