Aluminum is a low-density active metal with an affinity for oxygen. In nature, it exists in the form of compounds, and bauxite (mainly aluminum oxide) is the most common raw material for producing pure aluminum metal (an energy-intensive process that requires electrolytic reduction). As an active metal, aluminum is both flammable and has potential flammability. Specific chemical reactions can also release combustible gases. Aluminum can quickly form a stable oxide layer when exposed to air, and once coated, loose parts are commonly used in many daily applications.
However, in powder form, due to the increase in surface area, the risk factors increase, and the possibility of combustion is widely recognized. These characteristics that may pose challenges to production and processing also make aluminum powder widely used, including thermal spraying, paint production, additive manufacturing, catalysts, solid propellants, fireworks, and explosives.

Special aluminum alloys for additive manufacturing
The development of additive manufacturing has promoted the development of new components, particularly suitable for the unique melting and solidification characteristics of laser and electron beam additive manufacturing processes. Many of these alloys contain active elements such as rare earth Ti and Zr and require clean vacuum/inert gas melting and atomization technology provided by PSI 120 series HERMIGA production scale atomizers. Recently, IRT M2P installed such an atomizer at its metal powder factory in Uckange, France.
Post-treatment through fluidized bed reactor
FBR has a wide range of applications in processing metal powders and other powders. Applications include heat treatment, chemical reactions, and coating through bulk powder chemical vapor deposition (CVD), which can be expanded to commercially attractive volumes. The mass and heat transfer characteristics of fluidized beds make them particularly suitable for processing at high temperatures while allowing for easy pressure adjustment to optimize output. The application of 3D-printed aluminum powder is pervasive, covering almost all industries that require lightweight, high-strength, and high-performance components. Along with the continuous advancement of technology and the reduction of costs, it is expected that the application of aluminum 3D printing materials will become more widespread.
The application of 3D printing aluminum powder
Aerospace industry: In the aerospace field, aluminum powder 3D printing technology has been widely used due to its high requirements for material strength and lightweight. For example, aircraft wings, fuselage, and engine components can all be 3D printed using aluminum powder. This technology not only reduces the weight of components and improves efficiency but also makes it possible to manufacture complex shapes.

Automotive industry: Aluminum powder 3D printing technology is also widely used in the automotive field. Traditionally, aluminum alloys have been commonly used in automotive bodies, gearboxes, engine components, and more. Through 3D printing technology, the design of these components can be further optimized while maintaining or improving their strength and reducing their weight. Some car manufacturers, such as Ford, have begun to use aluminum additive manufacturing technology on a large scale to produce automotive parts.
Healthcare industry: Aluminum powder 3D printing also has specific applications in the healthcare field. For example, aluminum powder can be used to manufacture medical devices such as dental implants and orthopedic implants. Aluminum has good biocompatibility and corrosion resistance, making it an ideal choice for medical applications.
