What is Kovar?
| Element | Percent by Weight | Role in Alloy |
|---|---|---|
| Nickel (Ni) | 29% | Controls thermal expansion, enhances corrosion resistance |
| Cobalt (Co) | 17% | Stabilizes expansion characteristics, adds strength |
| Iron (Fe) | Remainder (~54%) | Provides the matrix for the alloy, affects magnetic properties |

Kovar is a low-thermal expansion nickel-cobalt ferrous alloy. It is stable in the dimension when attached to glass or ceramics. This renders it suitable to electronic and aerospace applications. Kovar has great strength, corrosion resistance, and thermal uniformity. It is commonly found in hermetic seals, sensors and vacuum systems. Its high stability in extreme temperatures gives it a long term stability and accuracy.
What is Kovar Machining?
Kovar machining is the process of shaping this alloy by precision CNC Swiss machining. It is a skillful process because the material is hard and tough. The engineers in CNC Swiss Masion work with sophisticated gadgets to ensure that the results are uniform and precise. Tool wear can be avoided by proper tool choice and controlled speed.
During machining, Kovar has a tendency to develop a built-up edge. This impacts on the quality of finishes and tool life. Minimizing the formation of edges is done by using sharp tools and proper lubrication. Expert control provides superficial surfaces and accurate dimensions during production.
What Is Kovar Material Machinability?
Kovar material machinability is the ease with which Kovar, a nickel-cobalt-iron alloy, can be cut and shaped, and which is characterized by its resistance to thermal expansion. Kovar is a difficult to machine metal because it is hard and work-hardens rapidly. The material finds application in industries where tight tolerances are required like in the aerospace, electronics and medical device manufacturing industries. Expert machining can be used to ensure surface integrity and dimensional accuracy throughout the production process. The special composition of Kovar enables it to fuse well with glass and other ceramics and therefore it is suitable in hermetic seals and vacuum applications. In CNCSwissMasion, the machinists are experts who apply sophisticated Swiss machining methods to deliver accurate and consistent outcomes with Kovar parts.
The Pros And Cons Of Kovar Machining
