Ni 20Al Powder Description:
Ni 20Al powder is an alloy composed of nickel (Ni) and aluminum (Al), with approximately 20% aluminum content. This powder is primarily used in high-temperature applications and coating technologies, offering the following key features and applications:
-
High-Temperature Stability: The Ni 20Al alloy exhibits excellent stability in high-temperature environments, effectively resisting oxidation and hot corrosion. This makes it suitable for applications that require prolonged exposure to elevated temperatures.
-
Excellent Mechanical Properties: This alloy possesses good strength and toughness, maintaining its mechanical properties even at high temperatures. It is ideal for components subjected to significant stress.
-
Self-Protective Oxide Layer: The presence of aluminum allows Ni 20Al to form a stable alumina (Al₂O₃) protective layer upon oxidation. This oxide layer can self-repair, providing long-term protection and extending the material's lifespan.
