要を生じ、合金の価額を上昇させる欠点がある。Conventionally, gold, silver, copper, and palladium were used as base alloys, and platinum, indium, and zinc were added to them to improve corrosion resistance, mechanical strength,
The melting temperature has been adjusted. However, while copper is added to improve mechanical strength and castability, copper is added to improve the discoloration and corrosion resistance of the alloy in the oral cavity. This is unfavorable from the viewpoint of adhesion and aesthetics. In order to improve this drawback, the patent application
No. 00648, Patent Application No. 1983-95969, Patent Application No. 1983
92380 and Japanese Patent Application No. 57-130285, alloys that do not contain copper are disclosed. There is a drawback that it becomes necessary to increase the indium content and/or increases the price of the alloy.

As a result, it was discovered that the objective could be achieved by blending boron copper, leading to this invention.
問題点を解決するための手段
本発明はボロン銅１〜５重量％、金２〜３５重量％、パ
ラジウム５〜１５重量％、銀２０〜５０重量％。Means for Solving the Problems The present invention contains 1-5% by weight of boron copper, 2-35% by weight of gold, 5-15% by weight of palladium, and 20-50% by weight of silver.

の色調及び加工性を保持するために必要な範囲である。It is a golden-colored dental casting alloy consisting of 10-26% by weight of indium and 1-5% by weight of zinc. The following percentages are percentages by weight. The composition of boron-copper is an alloy containing 1.6 to 2.2% boron and 98.4 to 97.8% copper. Boron copper 1-5%
is within a range that improves the mechanical strength and castability of the alloy without impairing its discoloration resistance and corrosion resistance. 2-35% gold is the range necessary to maintain the color tone and workability of the alloy.

が減少する。亜鉛は脱酸剤として必要な量を添加した。Palladium is added to increase the hardness without reducing the sulfidation resistance and toughness of the alloy. If it is less than 5%, there is no increase in hardness, and if it is more than 10%, there is a significant decrease in toughness compared to the increase in hardness. , 20 to 50% silver is within a range that improves the workability of the alloy. Indium is added to improve the sulfidation resistance and mechanical properties of the alloy, and at 10%, no effect of the addition is observed, and at 26% or more, the strength of the alloy decreases. Zinc was added in the required amount as a deoxidizing agent.
