| Abstract Scope |
Aluminum alloys have become indispensable in the automotive and electronic industries due to their exceptional properties, including a high strength-to-weight ratio, excellent formability, good corrosion resistance, and significant recycling potential. These alloys are increasingly utilized in heat exchangers, with the Al1000 and 3000 series being particularly favored for condenser tubes because of their superior heat efficiency and corrosion resistance. However, the ongoing quest for more efficient and lightweight systems has necessitated improvements in the corrosion resistance, mechanical properties, and formability of aluminum alloys. This study examines the effects of trace elements on the microstructure, mechanical properties, and corrosion characteristics of Al 3000 based alloys. The alloys were prepared using a gravity mold casting process and hot-extruded. The microstructure of the specimens was analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD). Mechanical properties were evaluated through tensile tests at room temperature. |
