Abstract

The present invention refers to a brazing filler, which fulfil the requirements for fusion nuclear reactors, that comprises a metal mixture consisting of copper powder mixed with titanium powder, or Cu-Ti alloyed powders, wherein the content of copper is between 40 and 85% of the total weight of the metal mixture, and wherein the brazing filler can optionally comprise an organic binder.
