Ever wondered if a metal could have similar properties to glass? Meet Kovar - the game-changing alloy that makes it all possible.
As an iron-nickel-cobalt alloy, Kovar is designed to have almost the same thermal expansion properties as borosilicate glass, allowing tight mechanical joints between two materials over a wide range of temperatures. Why is that important? Let’s dive in a little deeper.
Kovar, which is also known as Rodar, possesses similar properties to borosilicate glass, which is a bit different from your everyday glass. Borosilicate glass contains boron trioxide, giving it a low coefficient of thermal expansion—ultimately, it will not crack under extreme temperatures like standard glass does.
Some examples of borosilicate glass include:
Kovar is amazing when it comes to its unique properties. Compared to other metals, Kovar’s ability to maintain its integrity in extreme conditions gives it a big advantage. It’s particularly valuable in industries like aerospace, electronics, and scientific research.
Here are some specific advantages of Kovar applications:
Overall, Kovar excels in applications where a strong, durable, and thermally stable material is needed. Its unique properties make it a top choice for challenging environments where other metals might not make the test.
Metal spinning is a highly effective technique for shaping metal. Imagine a potter who’s shaping clay on a wheel—metal spinning is similar, but instead of clay, metal is used. The process involves rotating a circular sheet metal blank at high speeds while applying pressure with a tool to mold it around a mandrel—a cost effective way to create symmetrical objects like cones, cylinders, and domes with smooth finishes and high precision.
When it comes to Kovar, metal spinning offers some significant benefits:
