Product Series
Kovar
Product Introduction
Kovar alloy, also known as 4J29 alloy, has a density of 8.6g/cm3. It features a linear expansion coefficient similar to that of borosilicate hard glass at 20-450°C, a higher Curie point, and good low-temperature structural stability. The alloy can be easily wetted by glass due to its dense oxide film. Does not interact with mercury, and is suitable for use in instruments containing mercury discharge. Main sealing structure material for electric vacuum devices. This alloy is a typical internationally used Fe-Ni-Co hard glass sealing alloy and has been used to create airtight seals with harder Pyrex glass and ceramic materials.
