Where is spherical aluminum powder typically used? As production technologies continue to advance and improve, the manufacturing of aluminum powder has become increasingly standardized, leading to its expanding range of applications. Notably, many industries have particularly high demands for aluminum powder. Let’s take a closer look at spherical aluminum powder!
Where is spherical aluminum powder typically used? Before we find out, let’s first learn what aluminum powder is. Also known as aluminum silver powder or silver powder, it’s essentially a silvery metallic pigment. Pure aluminum foil is combined with a small amount of lubricant, then hammered and crushed into flake-like particles—these are subsequently polished to create the final product. Aluminum powder is generally characterized by its lightweight nature, high buoyancy, strong covering power, and excellent reflectivity of both light and heat.
Typically, we classify aluminum powder into air-atomized aluminum powder and nitrogen-atomized aluminum powder based on their production processes. Among these, spherical aluminum powder is specifically the nitrogen-atomized variety, characterized by its regular particle shape, uniform particle size, narrow distribution range, high tap density, and enhanced hardness.
Spherical aluminum powder has a wide range of applications, commonly found in industries such as metallic pigments, chemicals, metallurgy, refractory materials, composite materials, new building materials, and anti-corrosion products. Due to the inherent properties of aluminum powder, it is most frequently used for fingerprint identification and in the production of fireworks. Beyond these areas, spherical aluminum powder also plays a vital role in everyday life—such as in powder coatings, inks, plastic color masterbatches, printing processes, imitation gold paper, imitation gold cards, gold films, textiles, and more. However, since water-based paints and acidic or alkaline paints can cause aluminum powder to oxidize and turn black during use, they are not recommended for applications requiring acid-alkali resistance or scenarios involving exposure to rainwater.
That’s all for the knowledge about "Where spherical aluminum powder is typically used." We hope this information helps you make the right choice when selecting spherical aluminum powder. Stay tuned for more exciting industry updates straight from our team!
