How NiAlMo Alloy Powder Enhances High-Temperature Structural Stability

NiAlMo alloy powder combines the excellent oxidation resistance of nickel aluminide (NiAl) with the high-temperature strength of molybdenum (Mo), offering a powerful solution for structural applications in aerospace, power generation, and defense where thermal durability is critical.

Superior High-Temperature Mechanical Performance

NiAlMo alloy leverages the intermetallic structure of NiAl, reinforced by Mo-rich phases, to deliver:

• High strength and stiffness above 1000°C

• Low density compared to conventional Ni-based superalloys

• Strong creep and fatigue resistance under thermal stress

This makes it ideal for replacing heavier alloys in load-bearing components subjected to elevated temperatures.

Oxidation and Thermal Shock Resistance

NiAl forms a stable Al₂O₃ oxide layer that protects against:

• Rapid thermal oxidation in combustion environments

• Surface degradation during repeated thermal cycling

• High-temperature corrosion from exhaust gases or molten salts

This protective behavior enables NiAlMo parts to maintain long-term dimensional and structural integrity.
