Hydrogen Brazing

Hydrogen brazing is a metal joining technique where the parts (usually ceramic, steel or oxygen-free copper) are joined together in a high temperature hydrogen environment. The alloys (or braze filler material) are usually a combination of copper, nickel and precious metals.

Hydrogen brazing often leaves material very bright and shiny. The hydrogen acts as a cleaning agent to remove oxides.

Typical parts brazed in hydrogen include linear accelerator and waveguide components, cooling plates, medical devices, semiconductor components, and generally copper to stainless steel joints.
