Nickel Aluminide Powder (Ni₃Al) is a high-performance intermetallic compound known for its excellent high-temperature strength, oxidation resistance, and low density compared with conventional nickel-based alloys. Because of its ordered crystal structure and strong Ni–Al bonding, Ni₃Al demonstrates outstanding mechanical stability and corrosion resistance in demanding environments.
Ni₃Al powder is widely used in advanced structural materials, additive manufacturing, thermal spray coatings, and high-temperature components. It is particularly valued in applications where oxidation resistance and mechanical integrity at elevated temperatures are essential.
At VI HALBLEITERMATERIAL GmbH, we supply high-purity Ni3Al powder with controlled particle size distribution and consistent chemical composition, ensuring reliable performance for research, industrial manufacturing, and advanced materials development.

Our company’s high-purity nickel-aluminum (Ni₃Al) powder is primarily produced using a gas atomization process.
Steps:
1. First, high-purity nickel and aluminum raw materials are vacuum-melted. These elements are melted and alloyed in a vacuum induction furnace or inert atmosphere furnace, ensuring precise composition control and minimizing contamination from oxygen or other impurities. During the melting process, the alloy composition is carefully homogenized to obtain a stable Ni₃Al intermetallic compound phase.
2. Once the alloy melt reaches the required temperature and chemical homogeneity, the molten Ni₃Al alloy is conveyed to an atomizing nozzle. The liquid metal stream is then atomized within the atomization chamber by a high-pressure inert gas (typically argon or nitrogen). The powerful kinetic energy of the gas flow breaks the molten metal into numerous fine droplets.
3. These droplets rapidly solidify within the atomization tower. Due to surface tension during solidification, the particles naturally form a spherical powder morphology, significantly improving its flowability and packing properties compared to irregular powders.
4. After atomization, the powder is collected under controlled conditions and undergoes the following post-processing steps:
1. High chemical purity
2. Uniform intermetallic compound phase composition
3. Spherical particle morphology
4. Excellent powder flowability
5. Controllable particle size distribution
