Mingtai Aluminum introduce the advantages of Aluminum Alloy

Edit:Mingtai Date: 2019-05-23 14:58
The application of aluminum alloys for aluminum structure and the construction of aluminum alloys and large-scale concrete profiles have paved the way for the modernization and light weight of the metal-clad vehicles. The modernization and light weight of railway vehicles have also brought new developments in the development and application of aluminum. Question. From the aspect of materials, railway vehicles have high requirements for mechanical properties, processability, corrosion resistance, fatigue resistance and welding performance.
Therefore, 5000 series (such as 5005.5052.5083, etc.) and 6000 series (such as 6061.6N01. 6005A. 6082. 6063, etc.) should be selected according to different components, different uses and different parts. 7000 series (such as 7N01. 7003. 7005, etc.) Alloys. In the 1950s and 1960s, railway vehicles were usually welded with the outer panel of the 5083 alloy, the skeleton and the 7N01 gantry. However, in recent years, due to the large-scale (double-layered) and high-speed railway vehicles Lightweight, standardized and simplified construction and maintenance requirements, coupled with the successful development of large-scale integral siding and hollow complex thin-walled profiles, have promoted the application of large extruded profiles on railway vehicles.
These large-scale integrated precision extruded profiles are assembled by resistance spot welding and inert gas-shielded arc welding, which greatly saves man-hours and reduces weight, and the overall stiffness and local stiffness and the fatigue strength of the welded parts are comparable to those of the steel structure. Therefore, this ideal aluminum structural material creates favorable conditions for the modernization of railway vehicles.
