摘要

Nickel-based alloy for producing, by casting, components which have solidified in single crystal form, which contains the elements rhenium and tungsten, as well as further elements, such as aluminium, chromium and cobalt. The rhenium content is at least 2.3% by weight, and the weight ratio of the tungsten content to the rhenium content is at least 1.1 to at most 1.6.
