PURPOSE:To obtain an Ni alloy for ornamentation having superior workability, elasticity and suitability to plating by adding specified amounts of Al, Ti and C to Ni. CONSTITUTION:To Ni are added 0.01-1.0% Al, 0.01-0.8% Ti, <0.05% C and <=2% in total of one or more among Mn, Mg and Si as deoxidizing elements. The resulting alloy is heat treated so as to form intermetallic compounds such as Ni3Al and Ni3Ti, and it is age-hardened. A superior Ni alloy for ornamentation having superior suitability to plating as well as strength and elasticity improved by the formed intermetallic compounds is obtd.
