Metal powders are small particles of metal that are used in various applications, including manufacturing and 3D printing. These powders can be made from different metals, such as iron, copper, or aluminum, and are produced through processes like atomization or milling. Their fine size allows for better mixing and uniformity in products. In industries like aerospace and automotive, metal powders are essential for creating components with precise shapes and properties. They enable techniques such as powder metallurgy, where metal powders are compacted and heated to form solid parts. This method can improve material performance and reduce waste compared to traditional machining.
