Abstract

A high-temperature component made of a nickel super-alloy has the following composition in wt %: 11–13% of Cr, 3–5% of W, 0.5–2.5% of Mo, 3–5% of Al, 3–5% of Ti, 3–7% of Ta, 1–5% of Re and a remainder formed of nickel. A corresponding component which is also provided is formed of an alloy having a composition essentially similar to that mentioned above, but with the rhenium proportion replaced with 0.1–5 wt % of ruthenium.
