Kovar is a high performance alloy known for its low temperature expansion and excellent thermal conductivity, making it ideal for applications in electronics, aerospace, and other industrial applications Mehul Nickel Alloys is dedicated to to deliver high quality products, ensuring reliability and accuracy for their global customers.
Kovar is an alloy mainly composed of iron (29-17%), nickel (29-17%), cobalt (16-21%), and small amounts of manganese, silicon and carbon. It has excellent thermal expansion properties, which binds to glass, making it ideal for coating glass on metal. Technical properties include high strength, good ductility and thermal and shock resistance. Kovar foil is highly corrosion resistant and maintains its shape and strength at high temperatures. Advantages include glass compatibility for hermetic sealing, excellent performance and thermal stability, making it ideal for electronic, aerospace and electrical applications.

Kovar foil is mainly used in applications requiring strong metal-glass interfaces, as it has the same coefficient of thermal expansion as borosilicate glass It is widely used in the electronics and semiconductor industry for materials such as seals, copper poles and electrical feedthroughs. Cover’s properties also make it suitable for use in high-performance applications such as vacuum systems, aerospace, and military equipment. Its resistance to thermal and mechanical stresses, as well as its ability to maintain structural integrity under thermal conditions, makes it valuable for precision manufacturing.
