What are the characteristics of aluminum powder? As more and more aluminum pigment products find their way into our daily lives, aluminum pigments are gradually gaining wider recognition. We all know that the raw material for aluminum pigments is, in fact, aluminum powder. So, what exactly are the unique characteristics of aluminum powder? Let’s have Xuyang’s editor take you through a quick look!
What are the characteristics of aluminum powder? As widely known, aluminum powder is a silvery-white, grayish powder, also referred to as aluminum silver powder or silver powder in other regions. When observed under a microscope, aluminum powder appears as either perfectly spherical or irregular, branch-like particles—specifically, the spherical ones are classified as spherical aluminum powder. Different types of aluminum powder exhibit distinct properties. According to what our editor has learned, Xuyang Aluminum Powder can be categorized into three main types based on their applications: spherical aluminum powder, aerated aluminum powder, and coating aluminum powder. Now, let’s delve deeper into the unique features of each type of Xuyang aluminum powder.
1. Spherical aluminum powder
Xuyang's nitrogen-atomized spherical aluminum powder is produced directly from molten aluminum, perfectly meeting the diverse needs of various industries in terms of active aluminum content, electrical conductivity, ductility, and hardness. The spherical aluminum powder boasts uniform particle size with a narrow distribution range and exhibits high tap density. It features excellent sphericity, minimal impurities, and an active aluminum content exceeding 98%. With its silvery-gray appearance and ultra-low moisture levels, this product can be stored for extended periods without degradation.
2. Aerated Aluminum Powder
Aerated aluminum powder is produced via a dry ball-milling process under nitrogen protection, using national-standard aluminum as the raw material. The product boasts high active aluminum content, uniform gas-generation rate, easy dispersibility, and long shelf life. Alternatively, it can also be directly manufactured using molten aluminum as the raw material, effectively meeting the diverse industry requirements for active aluminum, electrical conductivity, ductility, and hardness.
3. Coating Aluminum Powder
The coating aluminum powder is produced via a dry ball-milling process under nitrogen protection. The product features uniform particle size distribution, excellent whiteness, superior gloss, and outstanding storage stability. Depending on the specific manufacturing process, it exhibits two distinct types of performance when incorporated into the coating film—namely, floating-type and non-floating-type aluminum powders.
That’s all for the editor’s introduction to "What Are the Characteristics of Aluminum Powder"—we hope it proves helpful to you. If you enjoy the editor’s articles, feel free to stay tuned for more updates.
