An Ni-Cr-W base alloy having superior creep strength and excellent corrosion resistance consists essentially of: by weight 21 to 25% of Cr, 18 to 25% of W, 0.5 to 2.0% Ti, 1 to 5% of Al, between zero and 0.2% of B, 0.025 to 0.5% of C, between zero and 0.3% of Zr and 0.3 to 3.0% of Ta, the balance being substantially Ni.
