What are the uses of aluminum powder? With advancements in technology, more and more industries are now entering the aluminum sector—but many people still have only a limited understanding of aluminum powder. Some aluminum powder is used in the chemical industry, while other types find applications as everyday materials. So, what exactly is aluminum powder used for? Let Xuyang’s editor provide you with a brief introduction.
What are the uses of aluminum powder? According to what I've learned, aluminum powder, also known as aluminum silver powder or silver powder, gets its name primarily from its silvery-white metallic luster. It appears as a grayish-white powder. As the particle size increases, the grayish hue diminishes; conversely, when the particle size decreases, the gray tone becomes more pronounced.
Generally, aluminum powder is primarily produced by atomizing aluminum using nitrogen gas. This process involves injecting compressed nitrogen through a nozzle to break down molten aluminum into fine droplets, which are then rapidly cooled by a large volume of nitrogen gas, transforming them into metallic powder. Finally, the powder is passed through a grading system to separate aluminum particles according to their different sizes.
Aluminum powder is commonly used for fingerprint identification and in the production of fireworks. Beyond these applications, aluminum powder also finds use in areas such as new building materials, the chemical industry, high-end metallic pigments, composite materials, refractory products, anti-corrosion materials, and pyrotechnics—and more. However, since water-based paints and paints containing acidic or alkaline components can cause aluminum powder to oxidize and turn black during use, it is not recommended for applications requiring acid-alkali resistance or exposure to rainwater.
