Alloys composed of 35.5 to 62.5 % silver, 4.1 to 11.0 % indium, 5 to 37.0 % gold, 0 to 40.0 % platinum, 0 to 35 % palladium, 0 to 9.5 % zinc, tin, gallium, copper, 0 to 2.0 % iridium, rhenium, rhodium, ruthenium, 0 to 5.0 % boron, cobalt, chromium, iron, germanium, niobium, nickel, silicon, tantalum , titanium, manganese, vanadium, the indicated percentages being percentages b y weight. On one hand, such alloys are inexpensive, and on the other hand, the ir physical properties with respect to the coefficient of thermal expansion mak e them suitable for veneering. Furthermore, they show a desired yellowish colo ur and improved corrosion resistance and mechanical properties.
