Product Description

Uniseal 42 Feni Constant Expansion Glass Sealed Alloy ribbon

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
