Nickel base superalloys containing Ni, Al, Mo and Ware provided with enhanced oxidation resistance through the addition of coordinated amounts of Cr, Ta and Y. The resultant alloys have oxidation resistance and high temperature mechanical properties which are superior to those of other superalloys. The alloys specifically contain in wt % Al 5.8-7.8 Mo 8-12 W 4-8 Cr 2-4 Ta 1-2 Hf 0-0.3 Y 0.01-0.1 Ni balance o |
