Product description
Details buyers use to confirm grade, use and supply.
Thermal Spray Grade Alumina Powder
Alumina (aluminum oxide) is a widely specified ceramic coating material valued for its hardness, chemical stability, and dielectric properties. This specific -140+325 mesh powder is prepared for thermal spray processes, where particle melting and impact velocity are critical to coating integrity.
The powder morphology and chemistry are controlled to suit high-velocity oxy-fuel (HVOF), atmospheric plasma spray (APS), and flame spray systems. Typical coatings exhibit excellent resistance to abrasive wear, high-temperature oxidation, and electrical breakdown, making them suitable for components in pumps, textile machinery, and electrical insulation.
Key Selection Considerations
When evaluating this powder for your process, consider the following points:
- Mesh size: The -140+325 cut balances melt characteristics with deposition efficiency in common thermal spray guns.
- Process compatibility: Confirm suitability for your specific equipment (HVOF, plasma, or flame) through a trial or technical consultation.
- Pack sizes: Standard packs include 5 kg tins, 10 kg tins, and 25 kg pails. Other packaging may be available on request.
