4J29 4J32 4J36 4J42 4J44 Kovar alloy sheet plate

4J29 alloy is also known as Kovar alloy. The alloy has a linear expansion coefficient similar to that of silicon boron hard glass at 20-450°C, a higher Curie point, and good low-temperature structural stability. The oxide film of the alloy is dense and can be well infiltrated by the glass. It does not interact with mercury and is suitable for use in mercury-containing discharge meters. It is the main sealing structure material for electric vacuum devices.
Product Description

According to the different matrix, super alloys are divided into iron-based super alloys, nickel based super alloys and cobalt based super alloys. Nickel base super alloy is called nickel base alloy for short.
