What is a KOVAR?
It is an alloy mixed mainly of Iron, nickel, and cobalt and has heat expansion qualities as heat-resistant glass. It is regularly fused to glass to form a gas seal. The coefficient of thermal expansion is the most essential mechanical feature of Kovar. The alloy is precisely fabricated and controlled to manufacture a coefficient of thermal expansion that is very close to that of hard glass (e.g. borosilicate glass) or ceramic, which means that it expands and contracts at the same rate.
The Sheet is a controlled expansion alloy. It is a Nickel Iron alloy with a combination of 29% Nickel, 17% Cobalt, and the remaining balance is Iron. The quality of extension of Kovar matches both the borosilicate glasses and alumina ceramics which makes it one of the most admired of the controlled expansion alloys for hermetic sealing applications.
It is produced to ensure good properties for machining and the deep drawing and is a porosity free product.
It not only possess thermal expansion similar to glass, but its nonlinear thermal expansion curve can often be made to match glass, thus allowing the joint to tolerate a wide temperature range.
