What is atomized aluminum powder? As aluminum powder becomes increasingly prevalent in heavy industries, many sectors have started paying attention to it. We all know that aluminum powder is categorized into ball-milled aluminum powder and atomized aluminum powder—and the latter demands a more sophisticated manufacturing process. Unfortunately, during the atomization process, many types of aluminum powder are prone to issues such as nozzle clogging, wire breakage, back-spraying, and "shooting"—unusual phenomena that can disrupt production. So, what exactly is atomized aluminum powder? Let’s dive into the details with Xuyang’s editor to better understand this specialized material.
What is atomized aluminum powder? According to what I've learned, when we're exploring aluminum powder, the first step is to understand the characteristics of atomized aluminum powder, followed by familiarizing ourselves with its production process. Typically, aluminum powder appears as a silvery-white to grayish powder—its gray hue diminishes as particle size increases, while it becomes more pronounced as particle size decreases. Meanwhile, during production, atomized aluminum powder is generally manufactured using a nitrogen-based atomization process.
So, what exactly are the processes involved? Let me break it down for you step by step. First, aluminum is melted into molten aluminum. Then, through a chemical reaction, compressed nitrogen gas is atomized into tiny droplets. These droplets are subsequently cooled to form metallic powder. Next, the powder undergoes a grading system that separates aluminum particles according to their varying size ranges—first by primary grading, followed by secondary grading. Finally, advanced dust removal technology ensures that the sorted, spherical aluminum powder is safely discharged. This, in essence, is the entire production process of atomized aluminum powder.
Atomized aluminum powder is a crucial raw material for producing aluminum silver paste. It has an extremely low moisture content, allowing for long-term storage. The product contains minimal impurities, with active aluminum content exceeding 98%, along with trace amounts of iron, silicon, copper, and water. Additionally, the aluminum powder features uniformly sized particles, a narrow particle size distribution range, and high tap density, making it widely used in fields such as metallic pigments, chemicals, metallurgy, refractory materials, advanced building materials, and anti-corrosion applications.
