Description
Technical Field
The invention belongs to the technical field of novel materials, and particularly relates to a novel vacuum welding material and a preparation method thereof.
Background
Vacuum welding, which means that workpieces are heated in a vacuum chamber and is mainly used for welding products with high quality and easily-oxidized materials. The vacuum welding furnace includes a pressure vessel having a cylindrical sidewall and a door sized and positioned to close one end of the cylindrical sidewall. The workpiece handling system is mounted on the pressure vessel door for supporting the metal workpiece for heat treatment or brazing. The workpiece handling system includes means for rotating the workpiece during processing. A vacuum system may be coupled to the workpiece such that the pressure inside the workpiece is less than atmospheric pressure during the brazing process.
Copper is a metal element, also a transition element, with the chemical notation Cu, copper, atomic number 29. Pure copper is soft metal, has red orange color band metallic luster when the surface is just cut, and has a purplish red simple substance. The ductility is good, and the thermal conductivity and the electric conductivity are high, so the material is the most commonly used material in cables and electric and electronic components, can also be used as a building material, and can form a plurality of alloys. Copper alloys have excellent mechanical properties and very low electrical resistivity, the most important of which are bronze and brass. In addition, copper is also a durable metal that can be recycled many times without compromising its mechanical properties.
