Description

technical field [0001] The invention belongs to the technical field of composite materials, in particular to a three-layer composite material for hard glass packaging and a preparation method thereof. In particular, it relates to a copper-clad composite material of fixed expansion alloy sealed with hard glass. Background technique [0002] With the development of modern science and technology, especially the rapid progress of vacuum electronic technology and microelectronic technology, the miniaturization of devices and the precision of structural components are constantly improving, and the requirements for materials sealed with hard glass are getting higher and higher. It should not only be matched and sealed with hard glass, but also have high electrical conductivity, thermal conductivity, and tensile properties. Since the sealing temperature of hard glass is 550-560°C, the expansion coefficient α (20～500℃) 5×10 -6 / °C. The commonly used metal material is 4J29 alloy (...
