High-temperature materials, based on alloyed intermetallic NiAl, have the following chemical composition (values in % by weight): 26-30 Al, 1-6 Ta, 0.1-3 Fe, 0.1-1.5 Hf, 0.01-0.2 B, 0-1 Ti, 0.1-5 Pd, with the remainder Ni and production-related impurities. The materials have excellent properties, in particular good strength and extremely high oxidation resistance, at very high temperatures of 1300° C., for example.
