PROBLEM TO BE SOLVED: To provide a Co-Cr base alloy for baking dental ceramics, which has good tensile characteristics such as strength, and hot forgeability, and can suppress oxidation due to baking of ceramics, that is, an alloy for baking dental ceramics having excellent oxidation resistance.SOLUTION: The alloy for baking dental ceramics having excellent oxidation resistance comprises Cr: 20% or more and 40% or less (% means mass%. Hereinafter, the same applies for chemical composition), Group 6 elements of the Periodic Table: 5% or more and 20% or less in total, Group 14 elements of the Periodic Table: more than 0% and 3% or less, B (boron): 0.005% or more and 0.110% or less, and the remainder including Co and inevitable impurities. |
