Vacuum /Pressure-less Sintering

Vacuum brazing is a precision metal joining process in which two or more metal components are permanently bonded inside a vacuum furnace using a filler metal (called a braze alloy). Unlike welding, the base metals are not melted. Instead, they are heated to a temperature above the melting point of the filler metal but below the melting point of the parts being joined. The molten filler metal flows into the joint through capillary action, creating a strong, clean, and highly reliable bond.

Because the process takes place in a high-vacuum environment, oxidation and contamination are virtually eliminated, making vacuum brazing one of the highest-quality joining methods available for critical applications.
