Kovar Alloy Welding Of Quartz Glass And Metal

Kovar alloy, also known as 4J29 alloy, has excellent welding and electroplating properties. This 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 wetted by glass. And it does not interact with mercury, suitable for use in instruments containing mercury discharge. It is the main sealing structural material for electric vacuum devices.

This alloy is a typical Fe Ni Co hard glass sealing alloy commonly used internationally. Stable performance after long-term use in aviation factories. Mainly used for glass sealing of electronic vacuum components such as emission tubes, oscillation tubes, ignition tubes, magnetrons, transistors, sealed plugs, relays, integrated circuit leads, chassis, casings, brackets, etc.

Our company can apply Kovar alloy welding to quartz glass and metal.
