Improved titanium alloys for dental castings and processes for the preparation thereof, characterized by the incorporation of predetermined small amounts of one or more noble metals, preferably ruthenium, or rhenium, and optional predetermined small amounts of one or more rare earth metals, preferably cerium. The present alloys have improved corrosion and tarnish resistance under the conditions of use, and the preferred compositions including rare earth metals have improved oxidation resistance which improves their receptivity and bonding strength for enamels, porcelain surfacing materials or caps.
