Ni₁Al₁ intermetallic: base
Al₂O₃: 31-34% wt.

apparent metallographic porosity: <1.0%
bond strength to carbon steel (@0.020" thick.): 7,000 PSI
hardness as-sprayed: 480-550 HV₃₀₀
typical as-sprayed roughness R_a: 80-110 μin
maximal coating thickness: 0.030 in
maximal working temperature: 1,650 °F

The coating has excellent resistance to high temperature erosion and corrosion, surpassing chrome carbide materials during service above 840°F. At these and higher temperatures, a hard protective Al₂O₃ scale develops even in "reducing" environments (H₂S, CO, etc.). Besides, with the increase of temperature, the Ni₁Al₁ intermetallic retains its mechanical properties better than metallic alloys. Resistance to acids and dew point corrosion are poor.
