Electric heating vacuum brazing furnace can brazing copper workpieces. Copper has good thermal and electrical conductivity, which enables it to quickly and uniformly transfer heat during vacuum brazing. Meanwhile, copper has a relatively low melting point, making it easy to form alloys with brazing materials, thereby achieving good metallurgical bonding.

When vacuum brazing copper workpieces, the following points should be noted:

Choosing the appropriate brazing material: In order to ensure good wetting and metallurgical bonding, it is necessary to choose brazing materials that match the copper material, such as silver based or copper based brazing materials.

Strictly control the vacuum degree: Copper is prone to react with oxygen to generate oxides, so the vacuum degree of vacuum brazing is crucial for welding quality. It is necessary to ensure that the vacuum degree meets the requirements to reduce the generation of oxides.

Reasonable setting of process parameters: including heating temperature, holding time, cooling rate and other process parameters, need to be reasonably set according to the specific requirements of copper workpieces and the characteristics of brazing materials to obtain ideal welding joints.

By selecting appropriate brazing materials and process parameters, and strictly controlling the vacuum degree, the electric heating vacuum brazing furnace can achieve high-quality welding of copper workpieces. This welding method has the advantages of high welding joint quality, few defects such as pores and cracks, excellent welding strength and corrosion resistance, and is widely used in aerospace, electronics industry, automotive manufacturing and other fields.
