In vacuum diffusion bonding, the metal parts to be joined are first placed in a vacuum chamber to create a vacuum environment. The metal is then heated above its melting point by a heating system to partially or completely melt it. Next, vapor is generated on the surface of the molten metal, and the vapor molecules diffuse freely in the vacuum.

Copper and stainless steel vacuum brazing is a processing method for brazing and connecting copper and stainless steel in a vacuum environment. It has the following advantages:

Aluminum vacuum brazing is mainly used to connect joints of aluminum materials. This method can be brazed at a lower temperature, avoiding the evaporation and oxidation of aluminum at high temperatures, thereby ensuring the quality of brazed joints. At the same time, brazing in a vacuum environment can reduce the influence of the atmosphere on the brazed joint, avoid problems such as oxidation and pollution, and improve the quality and reliability of the brazed joint.

Carbide vacuum brazing has the following advantages:
