Do you know what essential knowledge exists about the applications of aluminum powder? As industrial production demands grow, aluminum powder has become a crucial and widely used industrial raw material in modern industry. Today, the demand for aluminum powder is steadily increasing, with its applications spanning across multiple sectors—such as refractory materials, pigment coatings, ceramic alloys, and even chemical and metallurgical industries. So, many people might wonder: when producing aluminum powder, what key knowledge should we keep in mind regarding its applications? Let’s find out together with Xiaoyang’s editor!
What are the application knowledges of aluminum powder? According to what I've learned, aluminum powder—commonly known as "silver powder," a silvery metallic pigment—is made by adding a small amount of lubricant to pure aluminum foil, then crushing it into flake-like particles through pounding and compression, followed by polishing.
Aluminum powder is categorized into aerated aluminum powder and atomized aluminum powder. Atomized aluminum powder is essentially spherical aluminum powder, and typically, all aluminum powders are produced using ball mills. There are two main methods for manufacturing aluminum powder: the dry process and the wet process. At Xuyang Aluminum Powder, we exclusively employ the wet production process. In this method, petroleum solvents replace inert gases inside the ball mill, allowing the metallic aluminum powder to mix thoroughly with the solvent, forming a paste-like aluminum pigment—hence the term "wet process."
Actually, aluminum powder is lightweight, has excellent buoyancy, strong covering power, and outstanding reflectivity for both light and heat. Typically, the metallic aluminum powder used in pigments appears in a flaky, scale-like form. It's precisely this unique flaky particle structure that gives aluminum powder its distinctive metallic luster and superior shielding properties. Aluminum powder boasts a wide range of applications—used not only for fingerprint identification but also as a key ingredient in fireworks. Due to its versatile uses, high demand, and diverse product varieties, aluminum powder stands out as one of the major categories within metal pigments.
