Do you know what flake aluminum powder is? With the emergence of new materials, more and more products have been developed—and flake aluminum powder happens to be one of the more significant coating materials among them. So, do you understand what flake aluminum powder actually is? If so, let’s follow along with Xuyang’s editor to find out together!
Do you know what flake aluminum powder is? To better understand flake aluminum powder, let’s first look at its basic definition and composition. As far as we know, flake aluminum powder is a silver-white metallic powder made from pure aluminum—it’s also one of the most widely used metallic pigments today. Since the primary color of aluminum powder pigments is silvery gray, they’re commonly referred to in industry as “silver powder” or “aluminum silver powder.”
Typically, flake aluminum powder used as a pigment has a thickness of 0.1–2 μm and a diameter ranging from 1 to 200 μm. It is mainly categorized into two types: floating-type aluminum powder, which remains exclusively on the coating surface, and non-floating-type aluminum powder, which is distributed throughout the entire coating layer.
In terms of manufacturing processes, the preparation of flake-shaped aluminum powder pigments typically employs the widely used ball-milling method. Starting with aluminum powder as the raw material, the process begins with spray-drying to produce fine powders, which are then further processed through ball milling and chemical treatments to form tiny, flake-like particles. These particles are subsequently subjected to post-treatment steps such as classification, surface polishing, and surface modification, ultimately yielding aluminum powder materials of superior quality.
The applications of flake aluminum powder are quite broad, typically used in the preparation of paints, metallic enamels, vehicle coatings, inks, and varnishes—providing protective or decorative enhancements to finished products. For instance, it is applied to structural metals and steel components such as factories, bridges, and transmission towers, as well as in industries like automotive metallic metallic-effect topcoats and printed textile products.
