Applications
- Additive Manufacturing (3D Printing): Used in powder bed fusion and direct energy deposition techniques to create complex, lightweight structures.
- Pyrotechnics: Due to its high reactivity, aluminum powder is commonly used in fireworks, explosives, and propellants.
- Paints and Coatings: Aluminum powder is used as a pigment in metallic paints and coatings to provide a shiny, reflective finish.
- Metal Injection Molding (MIM): Aluminum powder is used to produce small, complex components in various industries, including automotive and electronics.
- Cold Spraying: Used in cold spray applications to repair or coat surfaces with minimal thermal distortion.
Aluminum Powder Reference
Aluminium powder metallurgy technology for high-strength applications
- A literature survey of aluminium powder metallurgy (PM) for high-strength applications was undertaken. Improvements in aluminium—base alloys made via ingot metallurgy (IM) are reaching the point of diminishing returns.
Purity: Typically 99% or higher, with some powders reaching 99.9% or more.
Shape: Can be spherical (from atomization) or irregular (from milling). Spherical is preferred for applications like 3D printing due to better flowability.
Aluminum powder is nearly pure and highly reactive, ideal for general applications like additive manufacturing and coatings, while aluminum alloy powder is mixed with other elements to enhance specific properties, making it suitable for demanding applications like aerospace and automotive components.
- Low Density: Aluminum is a lightweight metal, with a density of about 2.7 g/cm³.
- High Thermal Conductivity: Aluminum powder has good thermal conductivity, making it useful in thermal management applications.
- Electrical Conductivity: While not as conductive as copper, aluminum still has good electrical conductivity, making it useful in electrical components.
- Corrosion Resistance: Aluminum naturally forms a protective oxide layer, enhancing its resistance to corrosion.
