modulus at 1100°C (2012°F) (Table 5.1), creep strength (Fig. 5.3), and properties superior to other high-temperature alloys (Figs, 5.1-5.3 and Table 5.1). The high melting temperature of 1400°C (2552°F) enables the high-temperature properties of Ni3Al.

Ni3Al possesses good compressive yield strength at 650-1100°C (1202-2012°F) and superior fatigue resistance compared to many nickel-based superalloys.

Its hardness results in excellent wear resistance even at temperatures above 600°C (1112°F).
