Precious alloys are an important material group in dentistry because of their ease of use, excellent compatibility, favorable mechanical and physical properties, and application in ceramometal bonding. Although new precious alloys have been introduced in the past decades, frequently because of economic pressure, gold-based alloys remain a popular choice. Researchers have suggested that alloys should be chosen based on an understanding of the alloy system, selection of proven alloys from quality manufacturers, and consideration of the requirements of a given clinical situation.
