In industrial applications, materials with desirable properties play a pivotal role in shaping innovation. Kovar wire, an alloy renowned for its unique characteristics, is a great example of a precision engineered and reliable material.
In this blog post we will look at the distinctive properties of Kovar wire and explore its diverse applications in a variety of industries.
Composition and Properties
Kovar is a nickel-iron-cobalt alloy known for its thermal expansion characteristics, which closely match those of glass and ceramics. Composed of approximately 29% nickel, 17% cobalt, and the remainder iron, Kovar exhibits low thermal expansion over a broad temperature range. This property makes it a great choice for applications where a tight seal is required.
