Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing, which makes the research on the weldability of aluminum alloy also deepen.
Aluminum alloy powder is widely used in the civil aviation industry with its excellent properties of light density and high strength, and 3D printed aluminum alloy products are used in the domestic large aircraft C919. Aluminum alloy powder is widely used in the fields of 3D printing, laser cladding, and powder metallurgy.
