Nickel-Aluminum Powder [-170+325]

About Nickel-Aluminum [-170+325] Thermal Spray Powder

Nickel-Aluminum composite powder in the -170+325 mesh cut is engineered for thermal spray applications where a high-strength, self-bonding undercoat is required. The exothermic reaction between nickel and aluminum during spraying raises particle temperature, helping the coating fuse to clean, roughened surfaces. This bond coat then provides an ideal foundation for wear-resistant, corrosion-resistant, or thermal-barrier top coats.

Common spray processes include High-Velocity Oxy-Fuel (HVOF), atmospheric plasma spray (APS), and flame spray. The -170+325 mesh distribution is selected to balance flowability, deposition efficiency, and coating density. Buyers typically evaluate this powder for rebuilding worn shafts, preparing bearing journals, or as a bond layer under alumina, chromia, or tungsten carbide coatings.

Typical Applications

• Bond coat for ceramic top coats: Applied before alumina or zirconia layers to improve adhesion on steel components.
• Dimensional restoration: Used to rebuild worn or machined parts prior to finishing.
• Oxidation and corrosion protection: Provides a dense intermediate layer that resists high-temperature oxidation.
• General engineering repairs: Suitable for shafts, rolls, and pump components in heavy industry.

Selection and Handling Tips

Always confirm that your thermal spray system can feed and melt a -170+325 mesh powder efficiently. Store containers sealed in a dry environment to prevent moisture pickup, which can cause clumping and inconsistent feed. Sieve powder before use if it has been stored for extended periods. When requesting a quotation, specify your spray process, substrate material, and required pack size so we can recommend the most suitable grade.
