摘要
Gold/palladium alloys with a high gold content for dental applications ought, for biocompatibility reasons, not to contain any toxicologically objectionable constituents. The only non-noble metal constituent needed for particularly corrosion-resistant and biocompatible type 4 alloys is tin in amounts of from 0.7 to 5.8% by weight when the composition is kept within certain limits in the palladium/tin diagram. Alloys of this type contain besides gold and tin 6 to 25% by weight of palladium, 0 to 12% by weight of platinum and 0 to 2% by weight of iridium, rhodium and/or ruthenium. IMAGE
