Product Desciption
Uniseal 42 Glass Sealed Alloy strip
Iron nickel alloy is obtained at a given temperature range by adjusting the content of nickel internal energy and the expansion coefficient of different soft glass and ceramic matching a series of expansion alloy, its expansion coefficient and the Curie temperature increases with the increase of nickel content.The assembly is widely used in electric vacuum industry the sealing structure of the material
Chemical Composition in %, Invar
Basic physical constants and mechanical properties of the alloy:
Uniseal 42 alloy is mainly used for soft glass and ceramic seal, such as electron tubes, transistors and integrated circuit of fuses, framework, and the sealing plug
