Kovar (trademark of CRS Holdings, inc., Delaware ) is a nickel – cobalt ferrous alloy compositionally identical to Fernico 1, designed to have substantially the same thermal expansion characteristics as borosilicate glass (≈ 5 ppm /K between 30 and 200 °C, to ≈ 10 ppm/K at. Kovar (trademark of CRS Holdings, inc. Extensive quality controls are employed in the manufacture of this alloy to ensure. Shadow mask technology represents a critical component in precision manufacturing applications, particularly in semiconductor lithography and display manufacturing processes. Known for its controlled thermal expansion properties, Kovar maintains its structural integrity and forms reliable seals and connections with glass and ceramic materials. This makes it especially suitable for uses which require a matched-expansion seal between metal and glass parts. Thus kovar finds wide usage in the electronics industry for.
