1. What is nano aluminum powder?

Nano aluminum powder is aluminum metal produced as particles in the nanometer size range. Its extremely small particle size provides a substantially higher surface-area-to-volume ratio than conventional aluminum powder.

2. What particle sizes are available for aluminum nanopowder?

Common specifications can include particles below 20 nm, 20–50 nm, 50–100 nm, and 100–200 nm, with custom particle-size distributions potentially available.

3. Is nano aluminum powder pure aluminum?

High-purity grades can contain 99% to 99.99%+ aluminum. The actual specification should also consider the native oxide layer, oxygen content, impurities, and surface treatment.

4. What is the difference between aluminum powder and aluminum nanopowder?

The primary difference is particle size. Nano aluminum powder has significantly smaller particles and therefore much greater specific surface area, which can produce different electrical, thermal, catalytic, sintering, and chemical behavior.

5. Can aluminum nanopowder be supplied with a controlled surface or oxide layer?

Yes. Depending on the manufacturing process, aluminum nanoparticles naturally develop a thin oxide layer. Passivated or specially surface-treated grades may also be available for applications requiring improved stability or handling characteristics.

6. Can REG Metals provide custom aluminum nanopowder specifications?

Yes. REG Metals can source aluminum nanopowder to customer-specific requirements, including purity, particle-size distribution, morphology, surface condition, packaging, and documentation, subject to availability.
