Description

Super Alloys K94610 KOVAR Bar ASTM F15 Thermal Expansion

KOVAR Bar is also called sealing alloy or constant expansion alloy. The alloy has a linear expansion coefficient similar to that of borosilicate hard glass at 20~450 ℃, a high Curie point and good low temperature structural stability. The oxide film of the alloy is dense and can be well soaked by glass. It does not interact with mercury and is suitable for use in mercury containing discharge instruments. It is the main sealing structural material of electric vacuum devices.
