The invention provides a cobalt-based high-temperature alloy wire which is prepared from the following chemical components in percent by mass: 0.06-0.12% of C, less than or equal to 0.3% of Si, 1-1.8%of Mn, less than or equal to 0.015% of P, less than or equal to 0.015% of S, 19.2-20% of Cr, 9.5-10.5% of Ni, 14.2-15.5% of W, less than or equal to 2.8% of Fe, less than or equal to 0.4% of other impurities and the balance Co. By adding 19.2-20% of Cr, the cobalt-based high-temperature alloy wire has excellent corrosion resistance, and a condition that high-temperature strength is decreased as aresult of a double phase area as the content of Cr is too high to promote generation of an epsilon-Co phase and a sigma phase is avoided.

The content of W is controlled at 19.2-20%, so that it is ensured that a condition of prominent work hardening of the alloy, difficulty in cold processing and poor stability as the too high W content is avoided. As the cobalt-based high-temperature alloy wirecontains 9.5-10.5% of Ni, the tissue stability of the alloy is improved favorably, and precipitation of a Co7W6 phase is reduced. By adding 1.1-1.8% of Mn, the oxidation resistance of a Ni-Cr alloy isimproved effectively.
