Sintering is a key thermal process used to consolidate powder-based materials into components with the density, strength and dimensional stability required by the application. It plays a central role in powder metallurgy, but it is also used with hardmetals, cermets, selected ceramics and other advanced materials.
Before sintering, the material has already been shaped into a component, but its particles are not yet fully bonded. At some point, that structure must become a coherent part with the required physical and mechanical properties.

This is where sintering comes into play.

Vacuum brazing is used when metal components need to be joined with a high degree of cleanliness, strength and repeatability. By combining a controlled heating cycle with a low-pressure environment, the process reduces the risk of oxidation and contamination while keeping the base materials solid.

But what exactly happens during brazing, and why does performing the process inside a vacuum furnace make such a difference?

This article explains the basic principles of vacuum brazing, the main industrial applications and the process variables that determine whether a brazed assembly is clean, leak-tight and mechanically reliable.
