Low melting carat gold brazing alloys for jewellery manufacture

A study of Ag-Au-Ge-Si alloys
  • G. Zwingmann
Open Access


The Au-Ag-Ge-Si system has been investigated as a source of cadmium-free low melting carat gold hard solders but alloys of this type have been found to have restricted applicability. In particular, when applied to copper-containing alloys, brittle copper germanides and silicides are formed.
