ntroduction to Vacuum Brazing Technology
A metal joining technology performed in a vacuum furnace, where filler metal with a lower melting point than the base metal flows into the joint during heating, achieving a strong bond between parts without melting the parts themselves.
The entire process is carried out in a vacuum environment, effectively avoiding oxidation and contamination, and has very good welding on complex structures and high-precision parts.
Technical advantages
No melting of base material, almost no welding stress and deformation
Welding in vacuum environment, no need for cleaning or complicated post-processing
Dense and beautiful welds, excellent air tightness
Multi-station welding can be achieved simultaneously, suitable for mass production
Applicable Materials
Stainless steel, titanium alloy, high temperature alloy
Aluminum alloy, copper alloy, molybdenum, tungsten, etc.
It can also be used to connect dissimilar metals, and even to combine metals with ceramics and high thermal conductivity materials with high strength.
Application Areas
Aerospace, electronic packaging, new energy
Medical equipment, sensors, cooling modules
Heat exchangers, sealed chambers, precision
structural partsSuitable for industries with extremely high requirements for air tightness, cleanliness and welding accuracy.
