This innovative brazing process for copper uses new composite materials made of agarose, containing a filler alloy and a flow. They can be shaped by molding by powders injection.
The absence of the usual sintering and debinding stages allows the brazed joints to have a mechanical strength and a metallurgical quality similar to those obtained from conventional materials.
The developed compositions allow soft brazing (SnPb) and hard brazing (CuP) of pieces containing copper, however, the process could be extended to other materials.
