Therefore, in order to make up for such a drawback, Cu or the like is added. However, the amount of these additional elements has been relatively large in the past, and therefore there is a problem in terms of biosafety, and these alloys are not always required. It did not fully and simultaneously satisfy the various conditions that should be provided for dentistry and decoration, that is, biological requirements, chemical requirements represented by touch resistance, and mechanical requirements such as ease of casting and processing. . Therefore,
As a dental / decorative gold alloy, it is further desired to develop an alloy having good touch resistance, biosafety, good mechanical properties, and easy casting and processing.
