The alloy has the following composition, by weight: Gold: 17-25% Silver: 10-27% Copper: 40-60% Zinc: 3- 12% In addition to its appearance, the alloy disclosed has good corrosion and high tarnish resistance, good workability and castability and can be plated, if desired, and sized with conventional solders.
