It is primarily used in thermal spray coatings for the protection of various substrates against wear, corrosion, and high-temperature oxidation. The wire is composed of 80% nickel and 20% aluminum, and is commonly used to produce coatings that enhance the longevity and performance of industrial components exposed to harsh environments.

Other Names:

• Nickel-Aluminum Alloy Thermal Spray Wire

• Ni80Al20 Coating Wire

• Nickel-Aluminum Wire for Thermal Spray

Material Composition:

• Ni (Nickel): 80%

• Al (Aluminum): 20%

Appearance / Color:

• The wire has a silver-gray appearance with a shiny finish.

Wire Diameter:

• Available in a variety of diameters, including 1.6mm, 2.0mm, 2.5mm, and 3.0mm (custom sizes available upon request).

Flux Coating:

• No flux coating is needed as the wire is designed to melt and deposit directly onto the substrate during the thermal spraying process.

Characteristics

• High Corrosion Resistance: Ni80Al20 alloy exhibits excellent resistance to oxidation and corrosion at high temperatures, making it ideal for protecting components in harsh environments.

• Wear Resistance: The alloy’s hardness provides robust resistance against wear, making it perfect for high-stress applications.

• High Bonding Strength: The coating formed from Ni80Al20 has a high bond strength to the substrate, providing durable protection even under extreme conditions.

• Thermal Resistance: This alloy is particularly useful in high-temperature applications, as it forms a protective oxide layer when exposed to heat, improving the overall durability of the coated parts.

• Easy Application: The wire is designed for use in various thermal spray processes, including plasma spraying, flame spraying, and arc spraying, ensuring versatile application.

Technology

Ni80Al20 is designed for thermal spray techniques, where it is melted by heat and propelled onto the surface of the workpiece. As the spray material cools, it forms a strong, adherent coating that provides excellent protection against wear and corrosion.

• Thermal Spray Methods: Suitable for flame spraying, arc spraying, and plasma spraying.

• Spray Coating Properties: Once applied, the Ni80Al20 alloy forms a protective oxide layer on the surface, preventing further oxidation and enhancing wear resistance.

• Melting Point: The alloy melts at a relatively low temperature compared to many other high-performance alloys, facilitating easier spraying.

Theory

The alloy works by creating a durable coating that adheres to the surface of the substrate. When heated to its melting point, the wire is sprayed onto the substrate, and upon cooling, it forms a dense, uniform layer. The alloy’s high content of nickel and aluminum promotes the formation of aluminum oxide on the surface of the coated component, which improves its oxidation resistance and wear resistance.
