Aluminium powder is a fine, lightweight, and highly reactive powder made from aluminum metal. It finds applications in various industries, including metallurgy, explosives, pyrotechnics, paints, and additive manufacturing. While specific specifications may vary depending on the intended use, here are some common specifications for aluminium powder:

1. Particle Size: The particle size of aluminium powder is an essential parameter that affects its reactivity and application. The particle size can range from a few micrometers to several hundred micrometers. Common particle size ranges include:

   • Coarse Grade: > 150 micrometers
   • Standard Grade: 30 - 150 micrometers
   • Fine Grade: 5 - 30 micrometers
   • Ultrafine Grade: < 5 micrometers

2. Purity: Aluminium powder is typically available in different purity grades, with higher purity grades being more suitable for certain applications. The purity of aluminium powder is expressed as a percentage of the aluminum content. Common purity levels include:

   • Standard Purity: 99% aluminum content
   • High Purity: 99.7% aluminum content
   • Ultra-High Purity: 99.9% aluminum content or higher

3. Surface Area: The surface area of aluminium powder influences its reactivity and the rate of reactions it can participate in. Surface area is usually measured in square meters per gram (m²/g) or square centimeters per gram (cm²/g).

4. Bulk Density: Bulk density refers to the mass of aluminium powder per unit volume, typically expressed in grams per cubic centimeter (g/cm³). Bulk density can vary based on factors such as particle size, shape, and compaction.

5. Moisture Content: Moisture content indicates the amount of water present in the aluminium powder. It is often expressed as a percentage by weight.

6. Chemical Composition: Apart from aluminum, there may be trace amounts of other elements present in aluminium powder, depending on the manufacturing process. Common impurities can include iron, silicon, copper, and magnesium.

It's important to note that specific industries or applications may have additional or more stringent requirements for aluminium powder specifications. Therefore, it is recommended to consult the relevant industry standards, specifications, or suppliers for precise details based on your specific application.
