7003 Aluminum alloy is the most widely used non-ferrous metal structural material in the 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, and the research on the weldability of aluminum alloys has also deepened.
The wide application of 7003
Marine Aluminum Extrusion Profile
has promoted the development of aluminum alloy welding technology. At the same time, the development of welding technology has expanded the application field of aluminum alloys. Therefore, the welding technology of aluminum alloys is becoming one of the research hotspots.
7003 alloy is widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry. Using aluminum alloy to replace the welding of steel plate material, the structural weight can be reduced by more than 50%.
