Metal powder is a fine particulate form of metal, often produced through processes like atomization or milling. It is used in various applications, including additive manufacturing, where it serves as the raw material for 3D printing metal parts. The size and shape of the powder particles can significantly affect the properties of the final product. In addition to 3D printing, metal powders are also utilized in industries such as aerospace, automotive, and medical devices. They can be compacted and sintered to create solid components, allowing for complex geometries and improved material properties.
