PURPOSE: An alloy composition for a dental prosthesis and a method for manufacturing the same are provided to save money. CONSTITUTION: An alloy composition for dental prosthesis contains 2-20 wt% of gold, 25-35 wt% of palladium, 20-35 wt% of silver, 25-35 wt% of indium, 1-5 wt% of zinc, and 0.07-0.7 wt% of iridium. A method for manufacturing the dental prosthesis comprises: a step of forming a palladium and iridium alloy(S100); a step of adding gold, indium, silver, and zinc with the alloy and melting(S200); and a step of injecting the melted materials into a cast for molding(S300).치과 보철물용 합금 조성물 및 치과 보철물의 제조방법이 개시된다. 본 발명에 의한 치과 보철물용 합금 조성물은 금 2 내지 20wt%, 팔라듐 25 내지 35wt%, 은 20 내지 35wt%, 인듐 25 내지 35wt%, 아연 1 내지 5wt%, 이리듐 0.07 내지 0.7wt%를 포함하여 이루어진다.
