Vacuum brazing for aluminium products and copper stainless steel etc

What’s Brazing

Brazing is a metal-joining process in which two or more materials are joined when a filler metal (with a melting point lower than those of the materials themselves) is drawn into the joint between them by capillary action.

Brazing has many advantages over other metal-joining techniques, particularly welding. Since the base metals never melt, brazing allows much tighter control over tolerances and produces a cleaner connection, normally without the need for secondary finishing. Because components are heated uniformly, brazing consequently results in less thermal distortion than welding. This process also provides the ability to easily join dissimilar metals and non-metals and is ideally suited to cost-effective joining of complex and multi-part assemblies.

Vacuum brazing is carried out in the absence of air, using a specialized furnace, which delivers significant advantages:

Extremely clean, flux-free joints of high integrity and superior strength

Improved temperature uniformity

Lower residual stresses due to slow heating and cooling cycle

Significantly improved thermal and mechanical properties of the material

Heat treating or age hardening in the same furnace cycle

Easily adapted for mass production
