Do you know about flake aluminum powder and spherical aluminum powder? Nowadays, with the rapid development of various industries, more and more people are becoming interested in aluminum pigment products. As for aluminum powder—the raw material used to produce aluminum pigments—it can be broadly categorized into two types: flake aluminum powder and spherical aluminum powder. So, are you familiar with these two forms? Let’s take a closer look together!
Do you know about flake aluminum powder and spherical aluminum powder? As far as I understand, aluminum powder can be classified into flake-shaped and spherical types based on its structural form. To truly grasp these two products, it’s essential to first understand their definitions!
Typically, flake aluminum powder is an aluminum powder with a high aspect ratio—its structure is two-dimensional and planar—and it exhibits excellent shielding properties as well as unique angle-dependent effects. Flake aluminum powder has a wide range of applications, including use in coatings, high-end automotive topcoats, paints, inks, and even the printing industry, among others.
Spherical aluminum powder is a type of aluminum powder that features perfectly round, spherical particles. It has a wide range of applications, primarily in chemical raw materials, metallic coatings, metal pigments, paints, fireworks, the metallurgical industry, and more.
Spherical aluminum powder has relatively higher storage requirements compared to flake-shaped aluminum powder. Generally speaking, even small amounts of dust can lead to serious accidents if exposed to high temperatures in the air—so spherical aluminum powder is no exception and may even pose a greater risk, potentially triggering explosions. Additionally, it can react violently with gases like chlorine and fluorine. Therefore, when storing spherical aluminum powder, it’s crucial to keep the environment dry, stay away from ignition sources, and avoid direct sunlight. Everyone should pay close attention to the proper storage conditions for spherical aluminum powder—and, most importantly, prioritize their own personal safety.
