    摘要: Gold-palladium alloys with a high gold content for dental applications should, for reasons of biocompatibility, not contain any toxically dubious components. For particularly corrosion-resistant and biocompatible Type 4 alloys, tin is needed as the only base-metal component in amounts between 0.7 and 5.8 wt % if one remains within defined limits in a palladium-tin diagram of FIG. 1, for Pt values less than 2%. Such alloys contain, in addition to gold and tin, 6 to 25 wt % palladium, 0 to 12 wt % platinum and 0 to 2 wt % of at least one of iridium, rhodium and/or ruthenium.

    摘要: A yellow dental alloy is disclosed with high gold content for castings and ceramic veneers with an adjusted thermal expansion coefficient that does not produce any undesirable discoloration of the ceramic veneers and that is very hard. It contains 70 to 85% by weight gold, 5 to 13% by weight silver, 2 to 9% by weight platinum, 0 to 4.5% by weight palladium, 0.05 to 1% by weight iridium, rhenium, rhodium and/or ruthenium, 2 to 8% by weight copper, 0.1 to 6% by weight indium, zinc and/or germanium, and 0 to 4% by weight gallium, iron and/or tungsten.
