About Pure Aluminum Powder [-170+325] for Thermal Spray
Pure aluminum coatings are widely used to protect steel structures and components from atmospheric and saline corrosion. The -170+325 mesh particle size distribution is a standard specification for many thermal spray guns, offering a balance between consistent powder feeding and efficient melting in the flame or plasma jet.
This powder is suitable for applying bond coats, conductive paths, and sacrificial anodic layers. The resulting coatings exhibit excellent adhesion to prepared substrates and can serve as a standalone protective layer or a base for organic topcoats.
Process Compatibility
While the final process fit should always be confirmed with your equipment parameters, this mesh cut is commonly used in:
- Flame Spray: Traditional wire-flame alternatives; powder flame spray for field repairs and large-area coatings.
- Plasma Spray: Suitable for applying dense, well-bonded aluminum coatings in controlled environments.
- HVOF (High Velocity Oxygen Fuel): Can be used where a denser, lower-oxide aluminum coating is required, subject to parameter optimization.
We recommend discussing your specific gun model, nozzle configuration, and coating specification with our team to ensure this grade is the optimal match for your work.
